Abstract :
We propose and demonstrate a novel tunable external-cavity laser diode that simultaneously achieves rapid tuning rate and wide tuning range by electrical control. This contains new-type integrated laser diode, collimating lens, and diffraction grating mirror. The integrated laser diode consists of Fabry-Pe´rot laser diode and waveguide-type deflector, which can deflect the beam passing through the waveguide. By control of the current in the deflector region, maximum wavelength variation of 8.6 nm and sidemode suppression ratio of >35 dB were obtained.
