Title:
OPTICAL MODULE
Document Type and Number:
Japanese Patent JP2008197500
Kind Code:
A
Abstract:
To highly accurately control an optical wavelength, by reducing as much as possible a thermal contraction stress and a residual contraction stress to a substrate 1 caused by a difference between the linear expansion coefficients of the substrate 1 and a carrier 6, in an optical module obtained by bonding the substrate 1 comprising PLC and the carrier 6 holding it.
For the purpose of equalizing the linear expansion coefficients of the substrate 1 and the carrier 6, the carrier 6 is made of a material having the same property as that of the substrate 1, to mount the substrate 1 soldered onto the carrier 6.
