QD lasers go to market

摘要

First to offer QD edge-emitting lasers and epiwafers in commercial volumes (at March 2002's Optical Fiber Communications event) was Albuquerque-based Zia Laser, spun off in May 2000 from the University of New Mexico with professor Luke F Lester as chief research officer and Petros Varangis as chief of product development. It received $6m of venture funding in June 2001 and $5.4m in March 2003. Zia's MBE-grown "dots-in-a-well" (DWELL) structures (see Figure 4 [min]) include: 1.1510-1620nm InP-based QD broadband Tunable Gain Chip (TGC, sampled in April 2002), which has 40mW output for S-, C- and L-band tunable external-cavity lasers for long-haul and metro-area DWDM networks; 3. 1265-1340nm GaAs-based uncooled InAs QD DFB lasers (sampled in July 2002), which output 5mW at 10Gbit/s operation, allowing a reach of 80km in metro- and local-area networks.
