Abstract
PURPOSE: To achieve the stabilization of the temperature coefficient of phase constant by covering the circumference of an optical fiber of a diameter (d) having a core and clad comprising quartz glass to more than thickness (d) with a plastic material of ≤1.0kg/mm2 in Young's modulus.
CONSTITUTION: The circumference of an optical fiber of a diameter (d) having a core 1 and clad 2 comprising quartz glass is covered with a plastic material 3, such as silicone rubber, of ≤1kg/mm2 in Young's modulus, to more than thickness (d). If necessary, it is further covered with hard plastics 4 of a higher Young's modulus, to thickness of more than (d). In this case, the temperature coefficient of the optical fiber phase constant may be suppressed to about 6×10-6°C-1 intrinsic to quartz glass. Even when shrinkage of the plastics 3 occurs at a low temperature in the case of having the covering 4, the quartz part crooks in the plastics 3 of a lower Young's modulus, thus the optical length of the quartz part does not receive temperature change directly. Thereby, the stabilization of the temperature coefficient of the phase constant is achieved.
