A dual-grating InGaAsP/InP DFB laser integrated with an SOA for THz generation [PDF]
, 2016 We report a dual-mode semiconductor laser that has two gratings with different periods below and above the active layer. A semiconductor optical amplifier (SOA), which is integrated with the dual-mode laser, plays an important role in balancing the ...

Semiconductor Optical Amplifiers in avionics [PDF]
2011 IEEE Avionics, Fiber- Optics and Photonics Technology Conference, 2011 RSOAs have been demonstrated to operate within a WDM PON architectures over a >;60nm wavelength range with large path loss capabilities. Two RSOAs enable contiguous operation over the S, C and L bands; results indicate clearly that WDM architectures suitable for avionics with a PLC of >;25dB are possible with only two devices.
