Abstract : We present a method of direct measurement of spectral gain and corresponding data in photonic crystal waveguides defined in heterostructures on InP substrates. The method makes use of two photopumping beams, one for gain generation, the other for amplification probing. The results show a clear enhancement of gain at spectral regions of low-group velocity, namely at the edges of the so-called mini-stopband of a three-missing rows wide photonic crystal waveguide.
