Abstract

Optical amplifiers based on semiconductor diodes can enhance the performance of optical communications systems by permitting modulated and chirp-free pulse formation.¹ When based on single-stripe diodes, these have been limited to relatively low powers, injection locking of a laser amplifier array to a low-power master oscillator permits higher output powers but is sensitive to the Injected signal wavelength.² A traveling-wave amplifier made from a laser diode array is expected to reduce the sensitivity to the signal wavelength.
