 integration has been a major hurdle in photonics because current optical diodes need large magnets.
“A challenge for integrated photonic circuits is the realization of nonreciprocal elements like isolators and circulators. Most optical isolators and circulators are based on the magneto-optic Faraday effect, which requires the integration of (electro)magnets,” the researchers wrote in their paper.
Dr. Del’Haye and his team’s work has reportedly overcome this limitation by utilizing light stored in tiny chip-based glass rings to develop a diode.
Diodes are semiconductor devices that typically serve as one-way switches for electric current. They enable current to flow smoothly in one direction while restricting it from flowing in the opposite direction. Nearly every electronic circuit today uses diodes to manage the flow of current.
For the researchers to create diodes made of light, they used a technique that sends lots of light into a microresonator, or a glass ring on a silicon chip about the size of a human hair. By harnessing the circulating optical power in the process, the team was able to produce the diode effect.
“To create the optical diodes we used microrings that can store extremely large amounts of light. This meant that, even though we were only sending small amounts of light into these glass rings, the circulating power was comparable to the light generated by the flood lights in a whole football stadium – but confined into a device smaller than a human hair. The light intensities enable the formation of a diode via a light-with-light interaction called the Kerr effect,” Dr. Jonathan Silver, a higher research scientist at NPL, explained.
During their experiment, the researchers were able to demonstrate how the electromagnetic field of clockwise circulating light in the glass rings successfully blocked the counterclockwise circulating light.
“These diodes will, for the first time, open the door to cheap and efficient optical diodes on microphotonic chips, and will pave the way for novel types of integrated photonic circuits which could be used for optical computing,” Dr. Del’haye went on to say.
Aside from creating diodes made of light, the researchers’ study could also pave the way for new types of optical rotation sensors and optical memories to be developed.

To Protect the Arctic, Canada is First to Test Quantum Radar…...
I've discovered the problem is because of the password. It needs to be surrounded by quotes (because it contains special characters), which the sensor is not doing. I tested this by using the same email address and password that PRTG is trying to use, without quotes, and got the same error message. I then attempted the login and surrounded the password with quotes, and it worked.
Well - I am not from the PRTG/Paessler support - but I can tell you out of experience that especially IMAP and other mail related services might act differently - interpret the official RFCs differently - even thought just slightly.
It could be it is because your password has some very special character that might not translate well in the terminal emulation - or just because the IMAP server is a bit shaky.
Really thank you for sharing this! I will definitive keep it in mind - it would be nice to know what software is used on the server - if you do - cause this could actually help a lot as well!
"IMAP and other mail related services might act differently"
That's a very good point. And I agree about not wanting the quotes if they aren't supposed to be there.
To be clear, I didn't find a workaround, it still gives the error. I just used telnet to test what was happening. I didn't see any way of being able to change the sensor. My only solution is to change the password.
I'll let the developer of the IMAP server know what's happening.Longtime readers here will know how much I despise GPS devices where all of the cables come out the bottom of the device. It really limits how low on the dash the GPS can be mounted. Thankfully some GPS manufacturers have gotten the idea and are now shipping either powered mounts, relocated the cables, or are using right-angled USB cables.
But it sure isn’t a practical solution to purchase a new GPS device just for the cable. Thankfully, we got tipped off to a company that is selling right angled USB cable extensions. These cables are designed to work with a number of different GPS models and come with different “direction” angles. It appears most of them have been tested so they won’t put the GPS into USB mode, common with some power accessories.
The company is called USBFirewire.com and you can find their right angled USB cables here.

The story has no legs. The woman is wildly inconsistent, and she is plagued by suspicious activity (her praising of Putin), the changing stories of her and her second-hand witnesses, the lack of any serious vetting, etc.

As before when this first started showing up, Sanders' supporters were looking for anything they could to take Biden out. They even hooked onto claims from the farthest right wing media outlets (where she first put her story).

Denial, anger, and bargaining are all part of the grieving processLaurie Collyer’s Sunlight Jr. is her latest film following up 2006’s Sherrybaby starring Maggie Gyllenhaal.
Written and directed by Collyer, the film follows Melissa (Naomi Watts) and her disabled boyfriend, Richie (Matt Dillon). The pair manage to make it through hardships but are tested when Melissa loses her job, finds out she’s pregnant and her ex-boyfriend (Norman Reedus) comes to town.
Sunlight Jr. hits theaters on November 15th. It’ll be available on VOD on October 7th.DCL Enjoys Crowning Success at The Prince
March 24, 2014
The Prince public house in Colliers Wood has been acquired by PPR Estates through DCL – the leisure specialists – from Punch Taverns. The property development and Investment Company purchased the freehold off an asking price of £1m.
The 7,773 sq ft pub includes an open plan bar and central server on the ground floor with customer toilets, kitchen and washroom as well as an additional bar and function room to the rear. Living accommodation is situated on the first floor including six bedrooms living room, kitchen and bathroom. There is also an outside terrace and patio area to the side and rear of the building and it also benefits from a 2:00 am licence on Friday and Saturday nights.
Paul Tallentyre, Director of Pubs & Bars at Davis Coffer Lyons said: The Princes prominent location and spacious layout – which includes considerable outdoor space which is unusual for Greater London – meant that it was extremely popular with a wide range of buyers looking for change of use for redevelopment. PPR Estates is an exciting new investor/developer in the pubs market and has considerable funding in place. They are extremely active in the market at the moment and we are continuing to work closely with them to find further sites.Our organic bars are non-GMO project verified, certified gluten-free, and made in Canada only with real ingredients. From the farmers who grow our organic ingredients, to the staff who manufacture our products, we’re all dedicated to (some would say obsessed with) our vision of providing nutritious, wholesome snacks around the world.
Quite simply, we want you to love our bars. That’s why we use only the best ingredients – real nuts, organic fruit and sweet agave syrup, with no fillers, additives or artificial products – and show them off with our distinctive clear packaging.
When you choose a Taste of Nature snack bar, you’re making a smart choice for your body and your taste buds!
We are a privately owned and operated Canadian company established in 1989. Our two state-of-the-art facilities are located in Markham, Ontario, where our team develops and manufactures certified organic, non-GMO, gluten-free, kosher and vegan snack bars, as well as private label products.
Forests, mountains, oceans and big prairie skies have a way of making us feel connected to something much larger than ourselves. Canadians feel this more than most. Perhaps it’s the way we’re such nice, friendly people with an open-mindedness to see how different ingredients combine to make something none could on their own. In nature, we feel part of a whole.
