Paper Abstract

An array of twenty GaAlAs laser diodes was fabricated and RF and pulse modulation tests were conducted over a wide range in frequencies and pulse repetition rates. Measurements were made on the arrays to determine the dc voltage-current characteristics, optical output versus dc current, optical output beam distribution with off-axis angle, RF impedance versus frequency, RF optical waveform phase variation with off-axis angle, RF modulated optical output versus the RF drive voltage, RF modulated optical output for individual diodes in the array, optical waveform spectrum analyzer measurements, emission wavelength spectrum with and without modulation, effect of failed diodes on array performance, and the effects of long-term operation on array performance. All tests confirmed that the concept of requiring modulated diode arrays in applications requiring high optical power is acceptable.
