Millivolt-scale, high-speed electro-optic ring modulators for a wide cryogenic temperature range

Not Accessible

Your library or personal account may give you access

Abstract

We demonstrate III/V-on-Si modulators with ~10 mVpp modulation and Gbps speed over wide cryogenic temperature ranges (4K-60K). This is enabled by enhanced electro-optic effects of III/V quantum-wells and minimal III/V free-carrier freeze-out at cryogenics.
