International Classification:

G02B006/12

US Classification:

385 14, 385 15, 385 37, 385141

Abstract:

Waveplates formed of mesogen-containing polymers and planar lightwave circuits containing such waveplates. Polymers have sidechains containing mesogens such as biphenyl-containing groups. Polymers may have a glass transition temperature between 100 C and 300 C, and polymers may be stretched in excess of 150% to increase birefringence of polymer and provide thin films. Waveplates formed of stretched polymer films may have high biaxial birefringence.

International Classification:

G02B 6/12

US Classification:

385 14, 385 15, 385141, 385 37

Abstract:

Waveplate, planar lightwave circuit incorporating the waveplate, and method of making an optical device. The waveplate is formed of a mesogen-containing polymer film having a backbone and sidechains containing mesogen groups. The waveplate may be formed by producing a mesogen-containing polymer film having a nonzero birefringence of suitable dimensions for insertion into a planar lightwave circuit. The waveplate may be so inserted into an optical circuit of a planar lightwave circuit so that an optical signal traversing the waveplate is changed, for instance, to have two polarization states.

International Classification:

G09G 5/00
G09G 3/36

US Classification:

345207, 345 87

Abstract:

An electronic device may have a display with a brightness that is adjusted based on ambient light data from one or more ambient light sensors. An ambient light sensor may be formed from a semiconductor substrate such as a silicon substrate. Sensor structures may be formed in the silicon substrate. Conductive vias or other conductive paths may be used to interconnect sensor structures on a frontside surface of the ambient light sensor to contacts on a backside surface of the ambient light sensor. The ambient light sensor may be mounted on a substrate layer in the electronic device. The substrate layer may be a planar layer of glass or plastic such as a transparent display layer. The contacts of the ambient light sensor may be mounted to corresponding contacts on the surface of the substrate layer. The substrate layer may be a thin-film transistor layer in a liquid crystal display.
