Abstract : This program is dedicated to developing a low-cost full duplex module coupled to single-mode fiber. This module allows both transmit and receive over a single optical fiber. Using an InGaAsP/InP photodetector at the receiver end, and a single-mode InGaAsP/InP 1300 nm VCSEL as the transmission source. The key new technology in this module is the single-mode 1300 nm VCSEL, which should greatly reduce packaging and manufacturing costs compared to edge-emitting lasers. Although 1300nm room-temperature VCSELs do not exist today, the recent success of 1550nm VCSELs, as demonstrated by OCI and the University of California at Santa Barbara, suggest that 1300 nm VCSELs will work also. In the first two quarters of this program, OCI has investigated several different 1300 nm designs, which we discuss in the body of this report.
