Abstract
We demonstrate the integrated operation of a 16 x 1 wavelength-divisio n-multiplexed (WDM) source with distributed Bragg reflector (DBR) lase rs and electroabsorption modulators. By using repeated holographic exp osures and wet chemical etching, 16 different wavelengths from 1.544 t o 1.553 mum with an average channel spacing of 6 angstrom are obtained . A high-performance combiner is used to obtain a very uniform couplin g into the single-output waveguide, and with the integration of an opt ical amplifier an average optical power of -8 dBm per channel is coupl ed into a single-mode fiber.
