Transverse mode dynamics in vertical cavity surface emitting lasers excited by fast electrical pulses
We report measurements of the transient multimode dynamics of vertical cavity surface emitting lasers excited by short ~100–200 ps rise times, 1 ns duration! electrical pulses. Fast changes on the spatial distribution of the output power and strong mode competition are observed. Numerical simulations show that the observed dynamics are due to the partial overlap of the different transverse mode...

متن کاملMode Partition Noise in Multi-transverse Mode Vertical-cavity Surface-emitting Lasers
Relative intensity noise spectra of weakly index guided VCSELs in a multi{transverse mode regime are analyzed by using a model that takes into account all the transverse modes supported by the waveguide. Several resonance peaks are obtained in the noise spectra that correspond to the relaxation oscillation frequencies of the transverse modes. In is shown that for low spatially overlapping trans...
متن کاملVertical Cavity Surface Emitting Lasers
The goal of this project was to increase the power of vertical cavity surface emitting lasers and to convert their wavelength into the blue/ultraviolet and the infrared for sensing applications. We have increased the power to the multi-watt level and have generated several milliwatts of blue light using optical pumping. Electrical pump has been less successful, but we have identified the proble...
متن کاملLong-term spatiotemporal dynamics of solid-state lasers and vertical-cavity surface-emitting lasers
The number of Maxwell-Bloch equations describing the spatiotemporal evolution of solid-state and semiconductor-based lasers can be reduced when the temporal scales of the fields and atomic variables are very different. We demonstrate the existence of slow scenterd manifolds for models of solid-state lasers ssuch as Nd:YAGd and vertical-cavity surface-emitting lasers and determine reduced equati...
