Abstract: An apparatus for generating an oscillating reference signal at a reference frequency includes: (a) a light conveying element having a first end and a second end; the light conveying element conveying substantially all light received or reflected at one end to the other end; the light conveying element having a light transmission path intermediate the first end and the second end; the transmission path being related to the reference frequency; (b) a light transmitting element oriented to introduce light into the light conveying element at one end of the light conveying element; and (c) a light receiving element oriented to receive the transmitted light at one end of the light conveying element. The light conveying element, the light transmitting element and the light receiving element are implemented in a monolithic structure arranged on a single substrate.
