ABSTRACT:
A tunable laser capable of high speed operation is realized by modifying a tunable laser incorporating an N.times.N wavelength grating router to have an output waveguide positioned for capturing second order diffraction optical energy from the router free-space region. The second order diffraction-optical energy is supplied as the laser output at the desired wavelength to which the laser is tuned.
