Abstract: Embodiments of the present disclosure are directed toward techniques and configurations for an optical device having a semiconductor layer to propagate light and a mirror disposed inside the semiconductor layer and having echelle grating reflective surface to substantially totally internally reflect the propagating light inputted by one or more input waveguides, to be received by one or more output waveguides. The waveguides may be disposed in the semiconductor layer under a determined angle relative to the mirror reflective surface. The determined angle may be equal to or greater than a total internal reflection angle corresponding to the interface, to provide substantially total internal reflection of light by the mirror. The mirror may be formed by an interface of the semiconductor layer comprising the mirror reflective surface and another medium filling the mirror, such as a dielectric. Other embodiments may be described and/or claimed.
