Temperature-compensating component and for optic communication use identical Optical devices

摘要

Solve the problems, such as: excellent demultiplexing characteristic can be assigned to Optical devices for optic communication by providing temperature-compensating component. ;SOLUTION: temperature-compensating component includes that glass includes p 5+ 0.1% or more and 1% or more by Sn2+ cation %, the refractive index dn/dT -5 with temperature coefficient × 10-6/ °C 20-60 °C or smaller. ;COPYRIGHT:(C) 2016, JPO& INPIT
