Abstract
We have developed a four-channel AlGaInAs multiple quantum well, buried heterostructure, distributed feedback laser diode (MQW BH-DFB-LD) array for 1.3-/spl mu/m coarse wavelength division multiplexing (CWDM) systems. Fine detuning control by using a narrow-stripe selective metalorganic vapor-phase epitaxy (MOVPE) technique and an electron beam (EB) lithography technique enables 10-Gb/s operations in all channels at 85/spl deg/C. We obtained throughputs of more than 40 Gb/s in total. We confirmed low crosstalk operations for a 250-/spl mu/m pitch array. This is an attractive feature for fabricating compact transmitter modules.
