Microdot for transverse mode control in VCSEL
2022 Compound Semiconductor Week (CSW)(2022)
Abstract
The VCSEL device with a SiN microdot of 2um in diameter and 120nm in thickness showed a very strong mode suppression of 20dB on the 0
th
-order mode. The resulting spectral RMS was reduced significantly from 0.65nm to 0.47nm. Excellent PAM4 53Gbps eye diagram was obtained after 100-meter fiber transmission.
