ABSTRACT:
An integrated optical device includes a first block of transparent material having first and second side surfaces and a predetermined thickness between the first and second side surfaces. A mirror is applied to the first side surface of the first block and an optical filter is applied to the second side surface of the first block. A second block of transparent material is attached to the optical filter such that the optical filter is located between the first and second blocks. The attached first and second blocks have front and back cut surfaces intersecting the optical filter and the mirror at a predetermined angle. A first sheet of transparent material is attached to the front cut surface and a second sheet of transparent material is attached to the back cut surface. A method of making the integrated optical device is also described.
