Semiconductor Laser Device-Level Characteristics
… frequency responses for VCSEL and FP lasers, and relative intensity noise (RIN) for DFB and FP lasers have also been measured. Finally, the measurement of the frequency response of the optical pumping with 850nm VCSEL has been attempted.</p>

Characterization and comparison of optical source relative intensity noise and effects in optical coherence tomography
… investigates the effects of optical source noise in optical coherence tomography (OCT). While shot noise, thermal noise and relative intensity noise (RIN) (excess photon noise) constitute optical noise, RIN is the least understood and often the most significant factor limiting the …

Analysis and modeling of the effects of reflection induced noise on the performance of fiber optic communication systems
… to the interferometric conversion of laser phase noise into signal-dependent intensity noise. This relative intensity noise (RIN) is substantially higher than the intrinsic RIN of the laser. The power spectral density of the RIN and its impact on the performance of incoherent on-off keying digital …

The effects of noise in CATV distribution networks with star couplers and fiber amplifiers
Noise and distortion limit the channel capacity and degrade the system performance in AM-VSB SCM CATV Distribution Networks. The use of star couplers and fiber amplifiers is an approach to overcome these problems and meet the increasing demand for large capacity and high quality. The capacity and …

Investigation and development of a novel metrology standard for the measurement of relative intensity noise and frequency chirp of DFB lasers in optical networks
Laser diode Relative Intensity Noise (RIN) metrology capabilities have been developed and demonstrated, providing significantly improved sensitivity and accuracy than existing methods. This is a key parameter for laser components used in telecommunication systems due to the drive to reduce inherent …
