Patent ID: 7162127

Claim:
A polymeric optical waveguide module comprising: a submount, the submount including a first through-hole disposed at an end portion of the submount and a second through-hole disposed along a side portion of the submount; a light-emitting element disposed in the first through-hole; a polymeric optical waveguide film having a lower clad, a core, an upper clad, an optical path changing mirror surface provided at one end of the polymeric optical waveguide film and a guided light leakage portion on at least one of a lower surface of the core and an upper surface of the lower clad; and a monitoring light-receiving element disposed in the second through-hole, the monitor light-receiving element monitoring light emitted from the light-emitting element, wherein the light-emitting element, the polymeric optical waveguide film and the monitoring light-receiving element are aligned with each other by the submount so that the light emitted from the light-emitting element is reflected by the optical path changing mirror surface to be guided through the core and part of the light emitted from the light-emitting element is received by the monitoring light-receiving element via the guided light leakage portion.
