Relative Intensity Noise Suppression for RF Photonic Links

IEEE Photonics Technology Letters, 2008
We propose and experimentally demonstrate a novel technique to reduce laser relative intensity noise (RIN). A RIN suppression servo is usually implemented by inserting an intensity modulator in the optical path and controlling measured light intensity with a closed-loop servo system. We utilize the intensity modulator already present in a photonic link

Relative intensity noise in high speed microcavity laser

Applied Physics Letters, 2013
We have fabricated a high speed single mode microcavity laser of the form of oxide-confined vertical cavity surface emitting laser (VCSEL) and achieved an ultralow threshold current (ITH = 0.13 mA at 20 °C) with lasing wavelength at 837 nm. The optical spectrum of the microcavity VCSEL exhibits a mode spacing of 3.1 nm, which is corresponding to an ...

Relative intensity noise of a quantum well transistor laser

Applied Physics Letters, 2012
A quantum well transistor laser with a base cavity length L = 300 μm has been designed, fabricated, and operated at threshold ITH = 25 mA (0 °C). As a consequence of the inherent advantage of the picosecond base recombination lifetime, the transistor laser is able to achieve nearly a quantum shot-noise limited laser relative intensity noise (RIN) with ...

Relative intensity noise properties of quantum dot lasers

Semiconductor Lasers and Applications VIII, 2018
In this work, we theoretically investigate the relative intensity noise (RIN) properties of quantum dot (QD) lasers through a rate equation model including the Langevin noises and the contribution from the off resonance energy levels. It is shown that the carrier noise significantly enhances the RIN which can be further reduced by properly controlling ...

Measurement of relative intensity noise of semiconductor laser arrays

SPIE Proceedings, 1993
We report in this paper the measurement results of the relative intensity noise (RIN) in GaAs- AlGaAs laser arrays, comparing with that of single stripe lasers. The results are in agreement with the noise theory based on the rate equation. The experimental measurements include dependence of relative intensity noise on drive current, modulation ...

Relative intensity noise of unipolar intersubband semiconductor lasers

Advanced Semiconductor Lasers and Their Applications, 1999
Abstract An analysis is undertaken of the relative intensity noise (RIN) properties of intersubband semiconductor lasers. It is shown how the characteristic time constants of the laser dynamics determine the RIN of a variety of structures.

Relative intensity noise and timing jitter of Raman soliotns

Advanced Solid State Lasers, 2014
We investigate the dependence of the relative intensity noise and timing jitter of Raman solitons on optical fiber parameters, and obtain a Raman soliton at 1303 nm with 2.0 fs relative timing jitter.

Appendix 8: Relative-intensity noise (RIN)

1998
The relative-intensity noise (RIN) is an important quantity in determining whether lasers are acceptable for use in optical-commu nication systems. Its analytic study can require extensive algebra, but in this appendix the emphasis is on the physical significance of RIN and simulations using time-domain modelling to estimate its value for DFB lasers.

Relative intensity noise in cascaded-Raman fiber lasers

IEEE Photonics Technology Letters, 2005
Pump-to-Stokes and Stokes-to-Stokes relative intensity noise (RIN) transfer is discovered now for cascaded Raman fiber lasers (RFLs) with multimode laser pumping. We report on the first experimental study of this effect observed with two-stage phosphosilicate RFL and also propose its analytical explanation. It is shown that the peaks of radio-frequency

Low frequency relative intensity noise in semiconductor lasers

Optical Fiber Communication, 1990
Recent measurements show that low frequency relative intensity noise (RIN) can be substantially enhanced for multimode as well as single-mode lasers.1 This effect, which has important systems implications, is not predicted by conventional single-mode rate equation modeling of the laser's RIN, nor is it predicted in the multimode case if the ...
