Optical waveguide circuit module |
摘要 |
An optical waveguide circuit module of the invention is a highly reliable optical waveguide circuit module where cracks are not generated in an optical waveguide circuit chip housed even under a high temperature and high humidity environment. An optical waveguide circuit chip (25) comprises a waveguide forming region (10) formed on a substrate (1). The waveguide forming region (10) has a waveguide configuration sequentially connecting optical input waveguides (2), a first slab waveguide (3), an arrayed waveguide (4) made of a plurality of channel waveguides (4a) arranged side by side, the channel waveguides having a different length each other, a second slab waveguide (5), and a plurality of optical output waveguides (6) arranged side by side.
