Array of MEMS Tunable VCSEL for Multiple Wavelengths www.iosrjournals.org 96 | Page mechanical and electrical components. Simple VCSEL consumes more power as compared to MEMS VCSEL. We required smaller wavelength in the range of nm which a very less hence we used MEMS VCSEL.rray of MEMS Tunable VCSEL for Multiple Wavelengths www.iosrjournals.org 99 | Page Figure 7: Comparison of Voltage among the Cavities Figure-4 shows that the Voltage is 4.5391 V in the cavity as we applied 5V to the circuit. Similarly, Figure-5 shows that the voltage is 4.4463 V inside the cavity.
Breakthrough bleeding â bleeding or spotting between periods â is common when you use birth control pills to delay or prevent periods, especially during the first few months. Breakthrough bleeding typically decreases over time, however, as your body adjusts to the new regimen.
Combination birth control pills that contain less than 50 micrograms of ethinyl estradiol, a kind of estrogen, are known as low-dose pills. Women who are sensitive to hormones may benefit from taking a lower dose pill.ombination birth control pills come in different mixtures of active and inactive pills, depending on how frequently you want to have periods: 1  Conventional. 2  Conventional packs usually contain 21 active pills and seven inactive pills, or 24 active pills and four inactive pills.
