We demonstrate a record resonance frequency enhancement of 1.55-mum VCSELs from 10 GHz to 107 GHz under ultra-high optical injection locking. Detuning and injection-ratio dependence are characterized to show the broad applicability of the technique.
We have developed a cw 5-W 756-nm injection-locked Ti:sapphire laser and generated 1.1-W 378-nm radiation by its frequency-doubling in an external enhancement cavity, which is useful for the selective optical pumping of thalium isotopes.
We present an injection locked single-frequency laser with an asymmetric resonator for transversal mode control. To characterize the laser at the operation point the TEM00 mode content was measured in respect to the pump power.
A semiconductor based, CW injection stabilized, 2.46 GHz harmonically mode-locked laser using a feedback loop for long term stabilization is demonstrated. Optical supermode suppression of 36 dB and significant timing and amplitude noise reduction are observed.
We investigate conditions for optically coherent injection locking of a monolithic mode-locked semiconductor laser. An interferometric technique is used to quantify the relationship between modal detuning, pulse shape, and optical spectrum.
The optical spectrum and modulation response of wavelength-locked lasers are analyzed. The model is verified against WDM-PON system data. A maximum data rate resulting from a trade-off of chromatic dispersion and modulation damping is predicted.
