Abstract :
We have fabricated wavelength selectable lasers loaded with high-efficiency TiPt heater. Wavelength tuning by use of comb-shaped heater structure on DFB lasers array, temperature arise of SOA was suppressed, resulting in drastic improvement for the variation of optical output power at high temperature. Tuning range of 9.8 nm for wavelength selectable laser integrating four DFB lasers was realized with heater power consumption of as low as 0.36 W.
