Frequency stabilization of semiconductor lasers by resonant optical feedback.
With simple optical geometries a separate resonant Fabry-Perot cavity can serve as an optical feedback element that forces a semiconductor laser automatically to lock its frequency optically to the cavity resonance. This method is used to stabilize laser frequencies and reduce linewidths by a factor of 1000 from 20 MHz to approximately 20 kHz.
متن کاملFrequency Dynamics of Gain-Switched Injection-Locked Semiconductor Lasers
The frequency dynamics of gain-switched singlemode semiconductor lasers subject to optical injection is investigated. The requirements for low time jitter and reduced frequency chirp operation are studied as a function of the frequency mismatch between the master and slave lasers. Suppression of the power overshoot, typical during gain-switched operation, can be achieved for selected frequency ...
متن کاملSelf-injected semiconductor distributed feedback lasers for frequency chirp stabilization.
It is well known that semiconductor distributed feedback lasers (DFB) are key devices for optical communications. However direct modulation applications are limited by the frequency chirp induced by current modulation. We demonstrate that a proper external control laser operation leads to chirp-to-power ratio (CPR) stabilization over a wide range of modulation frequencies as compared to the fre...
متن کاملOptical heterodyne spectroscopy with frequency- and amplitude-modulated semiconductor lasers.
Optical heterodyne spectroscopy has been performed with GaAlAs diode lasers by modulating the injection current at frequencies up to 2.6 GHz. This extremely convenient modulation scheme results in simultaneous frequency and amplitude modulation of the laser output. When the modulated laser output probes a narrow absorption line, a characteristic heterodyne beat signal occurs. We show that the o...
متن کاملNoise and frequency chirping in external-cavity semiconductor lasers.
The noise spectra and frequency chirping of semiconductor lasers in the presence of arbitrary amounts of optical feedback are analyzed. Short external cavities with strong optical feedback are found to reduce the noise dramatically in semiconductor lasers, especially in the high-frequency regime. Frequency chirping is shown to be closely related to the nonlinear gain effect.
