Extremely low-noise facet-reflectivity-controlled InGaAsP distributed-feedback lasers

Extremely low-noise (relative intensity noise (RIN) < - 160 dB/Hz) was attained with the facet-reflectivity-controlled 1.3-μm wavelength InGaAsP buried-heterostructure distributed-feedback lasers, Noise increase due to the optical feedback was greatly suppressed. It was interpreted as a result of counterbalanced mode competition between distributed-feedback mode and Fabry-Perot mode.
