High-speed laser modulation beyond the relaxation resonance frequency limit.

چکیده
We propose and show that for coupling modulated lasers (CMLs), in which the output coupler is modulated rather than the pump rate, the conventional relaxation resonance frequency limit to the laser modulation bandwidth can be circumvented. The modulation response is limited only by the coupler. Although CMLs are best suited to microcavities, as a proof-of-principle, a coupling-modulated erbium-doped fiber laser is modulated at 1 Gb/s, over 10000 times its relaxation resonance frequency.

Microscopic modeling of second harmonic generation in quantum cascade lasers
During the last 20 years since the first Quantum Cascade Laser (QCL) [1] there has been substantial development. The long-wavelength limit exploiting intersubband transitions below the reststrahlenband with frequencies in the terahertz range [2] is currently an area of active research but efforts are also being made in the opposite direction towards the short-wavelength limit. As the lasing is ...
متن کاملRadio-over-fiber transmission from an optically injected semiconductor laser in period-one state
Nonlinear dynamics of semiconductor lasers has found many interesting applications in microwave photonics technology. In particular, a semiconductor laser under optical injection of proper strength and optical frequency detuning can enter into the dynamical period-one (P1) state through Hopf bifurcation. The resulting optical output carries a broadly tunable high-speed microwave modulation with...

متن کاملDirect modulation bandwidth enhancement of strongly injection-locked SG-DBR laser
Significant enhancement in the direct amplitude modulation bandwidth of an SG-DBR laser has been demonstrated under strong injectionlocking conditions, where the wavelength detuning between the master and the free-running SG-DBR slave laser is varied from 28.58 to 13.6 nm. It is demonstrated that the relaxation resonance frequency of a strongly injection-locked SG-DBR laser increases from 1.05 ...
متن کاملOptimal Operation Point for the Primary Harmonic Content of a Modulated Laser Diode
An analysis of harmonic contents of the optical output power for a laser diode is performed, and the results are described in details. The influence of external parameters such as modulation current, bias current, and frequency on the absolute value of power for each harmonic are fully described. The analysis is done by direct solution of rate equations of an arbitrary laser diode for carrier a...
