The results for a packaged 1.30-/mu/m InP/InGaAsP optical amplifier used to switch broad-band multilongitudinal mode signals are presented. Despite the absence of optical isolators and even with the introduction of additional external reflections (R/sub system/ /approx equal/ 1.0 percent), the optical fiber-to-fiber gain is stable over a large temperature range at resonance (/Delta/G /le/ 0.35 dB, /Delta/T = +- 0.75/sup 0/C at G = 5.7 dB). Although the amplifier is capable of higher levels of gain (G/sub max/ /approx equal/ 13 dB), it is viewed that stable gain, relative to variations in temperature and reflectivity, is more critical to the overall system. It has been found that a multilongitudinal mode signal can be amplified by a resonant amplifier without system degradation caused by mode-partition noise, and that junction heating requires a thermal stabilization period up to t/sub stab/ /approx equal/ 0.2 ms after the start of a current pulse.
