Single-mode optical Y junctions have been fabricated using silver-ion exchange in glass. Radiation losses are given for several different input conditions to the branch arms when the Y junction is used as an optical power combiner. A minimum radiation loss of 3 dB has been measured when only one branch arm is excited.
