Ultracompact Multi-Channel DWDM Laser Transmitter based on Super-Compact Grating On-A-Chip in Ruggedized Module

The proposed project will undertake the research, design, and development of key concepts and technologies for multi-channel Dense Wavelength Division Multiplexed (DWDM) laser transmitter with 10Gbit/sec modulation capability for civilian and military DWDM optical networks, based on super compact grating technology that has been developed in OptoNet. This project is proposed by a strong multidisciplinary team of industry and academic researchers, including device design and packaging experts from OptoNet Inc. and device physics and fabrication experts from Northwestern University. Phase I will focus on systematic design and feasibility studies of the proposed SCG (Super compact grating) based multi-channel high-modulation-rate compact DWDM laser transmitter to demonstrate the technical feasibility of the proposed technology for at least 2 wavelength channels. The feasibility will lay the ground work for Phase II. The proposed multi-channel DWDM laser chip will have the following attractiveness: (1). 8 Lasers Monolithically Integrated on a Single Chip; (2). Single Fiber Output with Multi Channels; (3) High Spectral Purity as good as a typical DFB laser; (4). High 10Gbits/sec Modulation Capability; (5) High Output Power of >10mW per Channel; (6). Integrated Built-In-Test Capability for Both Power and Wavelength; (7). Ruggedized packaging with wide operating temperature range and low module profile.
