InP-based devices integrating liquid crystals microcells for a tunable laser emission or a wavelength selective photodetection
2019 Compound Semiconductor Week (CSW)(2019)
摘要
Photonic devices with wavelength tuning capabilities are investigated with the use of liquid crystal microcells monolithically integrated onto the surfaces of photodiodes or VCSEL fabricated on InP based materials. For these two devices, we demonstrated that the detected or emitted wavelength can be selected on a tuning range of more than 70 nm in the case of the photodiode, and of more than 20 nm in the case of VCSEL.
