Abstract :
A phased-array-based multiwavelength laser has been realized on a chip area of 3.5×2.5 mm2. The device has nine channels, spaced at 400 GHz around a central wavelength of 1.55 μm. Its performance is characterized by a minimum threshold current of 101 mA, a maximum fiber-coupled power of 0.37 mW, and a linewidth of 21 MHz. In addition, simultaneous four-channel operation is demonstrated.
