Over-1000-channel hybrid integrated light source with laser diode arrays on a silicon waveguide platform for ultra-high-bandwidth optical interconnections

A multi-channel hybrid integrated light source with laser diode (LD) arrays on a silicon waveguide platform was developed. The configuration of the light source was optimized to minimize power consumption by considering of the thermal interference between the channels in an LD array and also between the LD array chips. On the basis of the optimization, an over-1000-channel light source was demonstrated to have an over-10-Tbit/s bandwidth optical interconnection. The hybrid integrated light source should be easily adaptable to a photonics-electronics convergence system for ultra-high-bandwidth interchip interconnections.
