摘要：
Multi-wavelength gain-coupled quantum well DFB laser array has been fabricated on an InP substrate by simply varying the ridge waveguide width of the element lasers. Owing to the gain-coupling effect, seven singlemode lasing wavelengths around 1.55 mu m with similar to 2 nm spacing were obtained simultaneously. The lasers had low threshold currents and small beam divergence.
