Abstract

We have recently reported on a new type of semiconductor laser, the Multi-stripe Array Grating Integrated Cavity (MAGIC) laser, that features an array of active stripes monolithically integrated with a diffraction grating.^1,2 We have already demonstrated the single wavelength operation of this device, showing that lasing can occur at discrete wavelengths selected from a precisely predetermined comb of values.^1,2 In this paper, we report on the simultaneous multiple wavelength laser emission from a single output port of a MAGIC laser. Simultaneous operation at up to four wavelengths is demonstrated, each wavelength being independently selected from a comb of nine wavelengths spaced at 2 nm intervals across the spectral range 1512 nm-1528 nm. Signal cross-talk is examined for the case of two- wavelength operation, and is shown to be approximately independent of wavelength spacing.
