PURPOSE:To obtain high accuracy and high reliability, by the use of a specified complex refraction crystal and a miniaturizing constitution method. CONSTITUTION:At the end surfaces of input and output optical fibers 8 and 9, a calcite plate 11 with a thickness of 1mm. in which an optical axis 10 is formed in a slant state, a rod lens 12, a single SBN crystal 13 with a thickness of 25mum, and a dielectric mirror 14 are bonded to form a unitary body by an optical bonding agent. The entire body is sealed in a protecting glass tube 15. The SBN stands for SrxBa1-xNb2O6(O<X<1). |
