2.05-/spl mu/m wavelength InGaAs-InGaAs distributed-feedback multiquantum-well lasers with 10-mW output power

摘要

Single-mode operation beyond 2.05-/spl mu/m wavelength has been achieved in InGaAs-InGaAs distributed-feedback (DFB) laser with four quantum wells. The continuous-wave output power is 10.5 mW at a drive current of 200 mA and 25/spl deg/C, The tuning range of the wavelength is between 2.051-2.056 /spl mu/m with a temperature tuning rate of +0.125 nm//spl deg/C.
