Abstract

We demonstrate the first fiber-coupled, broadband master oscillator power amplifier (MOPA) module where amplified spontaneous emission (ASE) light from an 840-nm superluminescent diode (SLED) is amplified by a low-confinement, broadband 840-nm semiconductor optical amplifier (SOA), generating power levels of more than 60 mW in single-mode fibers. The SLED and SOA are integrated, without an optical isolator in between, in a compact 14-pin Butterfly module on a temperature-stabilized optical bench. The highly-polarized ASE output has a polarization extinction ratio (PER) of more than 30 dB and a 10-dB bandwidth of more than 50 nm, resulting in a coherence length of 10 microns in air.
