Abstract :
A tunable pulsed UV laser holographic system is described which has the capability for ease of fabrication of multiplexed laser arrays, chirped gratings and millimetre-long distributed feedback lasers. First-order optoelectronic gratings (periods of approximately 2500 Ã…) have been produced over the entire surface of 2 in (50.8 mm) InP substrate wafers. Diffraction efficiencies above 90% and grating depths of 1400 Ã… are reported.
