La. Wang et al., INTEGRATED 4-WAVELENGTH DFB LASER ARRAY WITH 10 GB S SPEED AND 5 NM CONTINUOUS TUNING RANGE/, IEEE photonics technology letters, 4(4), 1992, pp. 318-320
A 1.5-mu-m, four-wavelength DFB laser array operating at a speed of 10
Gb/s and with a continuous tuning range of 5 nm for each laser has be
en demonstrated. An adjacent channel electrical crosstalk penalty of 0
.6 dB was measured, and the thermal tuning limitation was identified.
