High-frequency microwave signal generation using multi-transverse mode VCSELs subject to two-frequency optical injection.

چکیده
In this paper we report a new method of photonic generation of microwave signals using a multi-transverse mode VCSEL subject to two-frequency optical injection. Numerical simulations show that double injection locking involving two transverse modes can be obtained in these systems. We show that the higher-order transverse mode is excited with a much larger amplitude than that of the fundamental transverse mode. The comparison with the case of a single-transverse mode VCSEL subject to similar two-frequency optical injection shows that multi-transverse mode operation of the VCSEL enhances the performance of the photonic microwave generation system. Broad tuning ranges, beyond the THz region, and narrow linewidths are demonstrated in our system. The maximum frequency of the generated microwave signals can be substantially increased if multimode VCSELs are used instead of single-mode VCSELs.

Nonlinear dynamics of current-modulated multitransverse mode vertical-cavity surface-emitting lasers
An analysis of the nonlinear dynamics of current modulated weakly index-guided VCSELs in a multi{transverse mode regime is performed by using a model that takes into account all the transverse modes supported by the waveguide. Nonlinear dynamical behavior is studied when applying current modulation of high frequency and large modulation depth. Chaotic behavior is obtained in the multitransverse...

Turn-oo transients in current-modulated weakly-index-guided vertical-cavity surface-emitting lasers (VCSELs) are analyzed by using a model that takes into account all the transverse modes supported by the waveguide. Turn-oo transients strength is maximum for the current at which the VCSEL enters the multi-transverse-mode regime. Their strength signiicatively decreases for the multi-mode regime ...

We report greatly enhanced modulation response of multimode vertical-cavity surface-emitting lasers (MM-VCSELs), for the first time, using optical injection locking. A 3-dB bandwidth of 38 GHz and 54 GHz resonance frequency are achieved using a MM-VCSEL with a 3 GHz free-running bandwidth. We show that transverse mode selection can be attained with optical injection locking through frequency an...

We present detailed numerical simulations to clarify the important role that the nonuniformity of the transverse optical mode plays for the high-speed response of oxide-confined verticalcavity surface-emitting lasers (VCSELs). The comprehensive laser diode simulator, Minilase, as well as a one-dimensional rate equation model are used as simulation tools. It is demonstrated that, due to the nonu...
