Interconnecting the laser-diode (LD) arrays in a LD array module with a film-carrier reduces electrical crosstalk by about 8 dB. This value agrees well with the analytical value of 10 dB obtained by SPICE simulation. Application of this new technique to a prototype four-channel dual-electrode distributed-feedback LD array module for optical frequency-division-multiplexing achieved a flat response up to 2.3 GHz and a crosstalk of less than 30 dB for frequencies below 1 GHz
