Paper Abstract

We report the first demonstration of blue shift of optical pumping photonic crystal (PhC) laser. A femtosecond laser was used to pump the InGaAsP based two dimensional photonic crystal laser at room temperature. Linear dependence of the resonance wavelength with respect to the pump power is observed: dλ/dP=-1.5×10-2 nm/μW . Blue shift of overall 1.1nm was obtained with the increase power of pump laser. These results are in agreement with theoretical expectation while the carrier-induced index change is introduced into the PhC semiconductor laser. It shows a possibility that by proper wafer design and careful optimization, we may obtain wavelength stable photonic crystal laser, which is important in photonic integration.
