For low power consumption it is essential that the output from the laser diode (LD) is efficiently coupled to the optical waveguide, and there are several approaches reported in the literature, such as an evanescent coupling and butt-joint coupling, with and without spot-size converters (SSC).

However, stable lasing operation at high operating temperatures is problematic since the light sources are typically integrated on dielectric materials, which have poor heat dissipation and lead to a degradation in the laser performance. Photodetectors (PDs) are also key components for on-chip integration technologies, and both compound material systems and germanium (Ge) have been successfully employed as detector materials.
