Abstract
An optical submount has a circumscribed 4-faced depression on its bottom surface and a 3-faced depression at an edge of its bottom surface. An optical signal is transmitted through a face of the 3-faced depression and internally reflected from a face of the 4-faced depression. A set of additional depressions and intervening areas on the submount bottom surface act as an alignment mark.
