Improved crosstalk performance in a 10-wavelength 25 Gbps multichannel laser array transmitter module

Multiwavelength laser arrays are an important component for future wavelength division multiplexed (WDM) links and networks. In this paper we demonstrate a 10-wavelength multiwavelength transmitter with improved electrical and optical crosstalk performance. Simultaneous modulation of 10 lasers at 2.5 Gbps per channel is demonstrated with low crosstalk resulting in a 25 Gbps data rate into the fiber.
