WDM 200Gb/s Optical Transceiver Chip Modules with Quadrature Modulation and RF Transmission Capabilities based on WDM Electronic-Photonic Integration Platform

There have been significant interests from NASA in integrated optical transceiver chips for space optical communications, in particular space-qualifiable 1550nm laser transmitter and receiver with optoelectronic laser, modulator, and detector, that are capable of data rates from 1Gb/sec to 200Gb/sec. The power efficiency shall be better than 10W per Gb/sec and weight less than 100g per Gb/sec. In addition, hybrid RF-optical technologies are sought, and technology based on integrated photonic circuit solution is strongly desired.To address the abovementioned interests, our proposed works will focus on realizing 100-200Gb/sec high-data-rate Wavelength-Division-Multiplexed (WDM) photonic transceiver module that will be able to meet the above NASA requirements, based on a few key technologies we have developed including: (a) WDM Laser Transmitter with Concurrent Wavelength Locking Capability; (b) Ultra-Compact Wavelength Mux/DeMux; (c) Integrated Narrow Linewidth Laser; (d) Integrated 20-40Gb/sec Modulator with low voltage of ~1.5V; (e) Ruggedized Wide-Temperature-Range Chip Packaging Module with large operating temperature range of -40oC to 100oC.
