Wavelength selectable laser with inherent wavelength and single-mode stability

We present a 8/spl times/200 GHz wavelength selectable laser that has inherent wavelength and single-longitudinal-mode stability. The wavelength stabilization is accomplished by the long cavity and passive intracavity chirped waveguide grating router, and the single-mode stabilization is accomplished by gain nonlinearities, aided by minimization of cavity length and router passband width.
