SLD-based light-emitting modules at 1300 nm operable in temperature range from −55°C to +125°C

Using single-mode fiber for harsh environment and two-stage thermoelectric coolers in standard Butterfly package, superluminescent diode (SLD)-based modules with 1300 nm emission median wavelength operable in extremely wide temperature range were realized. The results of performance and stability tests of the devices are presented.
