Coherent Optical Transceiver using Circular Polarization-Based Balanced Mixing, Phase I

Completed Technology Project

Project Introduction

Coherent Optical Transceiver using Circular Polarization-Based Balanced Mixing, Phase I
Boulder Nonlinear Systems (BNS) proposes to use its electro-optic component and subsystem expertise to transition a patented heterodyne detection scheme previously conceived by BNS for LIDAR to application in satellite based laser communications. The proposed effort will leverage past and present contracts in free space optical communication and space qualification of components. The proposed transceiver, which can be demonstrated with COTS components, is independent of platform orientation and path length differences. In addition BNS will investigate replacing the transceiver's conventional crystal modulator with a low voltage polymer electro-optic modulator. The proposed work plan entails demonstration of the path length and orientation insensitivity of the detection scheme as well as implementation of an electro-optic polymer based modulator for 1550 nm laser radiation. In addition to the proof of principle demonstration, Boulder Nonlinear Systems proposes to perform a design study to determine the size, weight and power of the transceiver subsystem and develop a road map for space qualification of the technology. A follow-on Phase II effort would result in a prototype laser communication subsystem with potential for satellite based application. More »
