Simultaneous operation of ten-channel tunable DFB laser arrays using strained-InGaAsP multiple quantum wells

Simultaneous operation of a ten-channel tunable multisection lambda /4-shifted distributed-feedback (DFB) laser array using strained-InGaAsP multiple quantum wells is described. The lasing frequencies of the ten channels are all set in a single 10-GHz space, with each channel maintaining a narrow linewidth of less than 2.3 MHz. This array has potential applications for optical frequency-division-multiplexing systems.<
