Patent number: 9151664Abstract: An optical submount has a circumscribed 4-faced depression on its bottom surface and a 3-faced depression at an edge of its bottom surface. An optical signal is transmitted through a face of the 3-faced depression and internally reflected from a face of the 4-faced depression. A set of additional depressions and intervening areas on the submount bottom surface act as an alignment mark.Type: GrantFiled: August 3, 2012Date of Patent: October 6, 2015Assignee: HOYA Corporation USAInventors: Rolf A.

Patent number: 9151890Abstract: An optical apparatus comprises: source, primary, and secondary waveguides formed in waveguide layers on a substrate; a light source; and an optical waveguide tap. The light source launches a source optical signal along the source waveguide. The tap divides the source optical signal into a primary optical signal in the primary waveguide and a secondary optical signal in the secondary waveguide. The secondary optical signal emerges from the secondary waveguide to exit the waveguide layers at the substrate edge or to propagate within the waveguide layers as a stray optical signal without confinement by any waveguide. The stray optical signal propagates thusly unconfined into the open mouth of an optical trap that comprises one or more lateral surfaces formed in the waveguide layers and an opaque coating on the lateral surfaces, and comprises a spiral region of the optical waveguide layers with an open mouth and closed end.Type: GrantFiled: August 31, 2014Date of Patent: October 6, 2015Assignee: HOYA Corporation USAInventors: Peter C.

Patent number: 8995813Abstract: An optical apparatus comprises: a waveguide substrate, optical cladding formed on the substrate; a waveguide core formed within the cladding, an optically absorptive layer formed within the cladding, and a linearly polarized light source. The waveguide core includes an attenuating segment thereof, and the absorptive layer is formed near the attenuating segment of the core. The core and cladding are arranged to form an optical waveguide that supports a propagating optical mode. The absorptive layer is positioned near the attenuating segment of the core so as to spatially overlap a portion of the optical mode. The extent of the overlap results in a designed level of optical loss per unit distance of propagation of a linearly polarized optical signal along the attenuating segment of the optical core in the optical mode without substantial alteration of the polarization state of the optical signal.Type: GrantFiled: November 17, 2012Date of Patent: March 31, 2015Assignee: HOYA Corporation USAInventors: Rolf A.
