Abstract
Semiconductor optical amplifiers have been used successfully for high power lasers employing the master-oscillator power-amplifier (MOPA) configurations [1,2]. We show in this paper that the semiconductor optical amplifier also can be used with a light emitting diode (LED) to construct a high-power broad-spectral-band source. Hybrid combinations of LEDs and semiconductor amplifiers have been reported previously as light sources for subcarrier-multiplexed (SCM) fiber access systems [3,4] and for sensing applications [5]. Here we report on a monolithically integrated LED-amplifier which has been fabricated for the first time. We also demonstrate the use of the monolithic LED-amplifier as a potentially low-cost WDM (wavelength-division-multiplexed) transceiver in a spectrally sliced fiber access systems.
