Abstract
The present disclosure generally relates to semiconductor devices for use in optoelectronic/photonic applications and integrated circuit (IC) chips. More particularly, the present disclosure relates to semiconductor devices having a reflector and a photonic component and a method of forming the same. The present disclosure provides a semiconductor device having a substrate, a photonic component arranged above the substrate, a bottom reflector arranged above the substrate and positioned below the photonic component, in which the bottom reflector has a plurality of grating structures configured to reflect electromagnetic waves towards the photonic component, and a top reflector arranged above the photonic component, in which the top reflector has a plurality of grating structures configured to reflect electromagnetic waves towards the photonic component.
