Honeycomb filter

In a cross section perpendicular to a central axis direction of the honeycomb substrate, cells are arranged so that a periphery of an inlet plugged cell is surrounded with four rectangular outlet plugged cells and four square outlet plugged cells, and in the cross section, a partition wall center distance a, a partition wall center distance b and a partition wall thickness t satisfy the following equation (1). Additionally, an amount of a catalyst per unit volume of partition walls which is loaded onto the partition walls defining the rectangular outlet plugged cells and the inlet plugged cells is larger than an amount of a catalyst per unit volume of the partition walls which is loaded onto the partition walls defining the rectangular outlet plugged cells and the square outlet plugged cells.0.95<b / at<1.90  (1)

Semiconductor optical waveguide device and method for manufacturing the same

ActiveUS20140254998A1Easily propagateLarge optical coupling efficiencySemiconductor/solid-state device manufacturingCoupling light guidesLight waveElectrical conductor
A semiconductor optical waveguide device includes a substrate having a first area and a second area, and first, second, and semiconductor mesas on the substrate. The first semiconductor mesa includes a cladding layer and a first mesa portion on the second area, the first mesa portion including first and second portions. The second semiconductor mesa includes an intermediate layer, a first core layer, and first and second mesa portions on the first and second area, respectively. The third semiconductor mesa includes a second core layer, and first and second mesa portions having a greater width than that of the second semiconductor mesa. The first portion of the first semiconductor mesa has a substantially the same width as the second mesa portion of the second semiconductor mesa. The first core layer is optically coupled to the second core layer through the intermediate layer disposed between the first and second core layers.

Temperature control element temperature control component, and waveguide opical module

InactiveUS20050141845A1Good wavelength demultiplexing characteristicLower the temperature of the plateCoupling light guidesOptical waveguide light guideLight waveEngineering
A temperature controller and temperature control element, whose plate-surface temperature distribution is highly homogeneous, which can be used in a waveguide type optical module. In a waveguide type optical module a temperature control element is supported on a pedestal inside a casing and an optical waveguide is mounted on the temperature control element. The temperature control element includes a plate having a heater or heat absorber provided on the non-heating side thereof or buried therein. The pedestal is provided to support the plate mainly in contact with the non-heating side of the plate. A total area of contact of the pedestal with the plate including an area of contact with the heater or heat absorber is set to over 30% of the area of the non-heating side of the plate and a sum of surface roughness of the pedestal and those of both the plate and heater is set to over 0.05 μm.
