Title:
OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2021/084602
Kind Code:
A1
Abstract:
This optical module (1) comprises: a Peltier module; an optical semiconductor element (3) mounted on the Peltier module; and a driver 4 for driving high frequency lines (37, 38) of the optical semiconductor element (3). The optical semiconductor element (3) comprises optical circuits (31-36) provided with an optical interferometer function, and the high frequency lines (37, 38). The cooling capacity of the Peltier module in a region in the vicinity of the driver 4 is greater than the cooling capacities of other regions.
