Title:
OPTICAL MODULE
Document Type and Number:
WIPO Patent Application WO/2008/035430
Kind Code:
A1
Abstract:
In a surface mounting optical module, reliability to temperature and humidity changes is easily improved at low cost. Fiber collimators (101-106) are respectively arranged on a plurality of positioning grooves (61-66) formed on the upper surface of one common substrate (50). A plurality of block-shaped optical elements (wavelength selection filters (71-74), optical path correction members (81, 82) and optical path correcting members (91, 92)) are arranged on the upper surface of the substrate so that light transmits in spaces between the fiber collimators through the optical elements themselves. The upper surfaces of the optical elements and the fiber collimators are covered with connecting members (311, 312, 371, 381, 391), and the lower surfaces of the connecting members are adhered and fixed on the upper surfaces of an optical components below.
