Abstract:
A supercontinuum light emitting device (100) comprises an effectively CW light source (110) producing light of wavelength 1 within a specified bandwidth and a nonlinear fiber (120) optically coupled to the light source (110). The nonlinear fiber has a plurality of fiber segments (13O i ) with different zero dispersion wavelength o i , where each successive fiber segment has zero dispersion wavelength o i , which is larger than the zero dispersion wavelength of the preceding fiber and the zero dispersion wavelength of the first fiber segment is within ±20 run of 1 .
Abstract:
A multi-wavelength distributed Bragg reflector (DBR) semiconductor laser is provided where DBR heating elements are positioned over the waveguide in the DBR section and define an interleaved temperature profile that generates multiple distinct reflection peaks corresponding to distinct temperature dependent Bragg wavelengths associated with the temperature profile. Neighboring pairs of heating elements of the DBR heating elements positioned over the waveguide in the DBR section are spaced along the direction of the axis of optical propagation by a distance that is equal to or greater than the laser chip thickness b to minimize the impact of thermal crosstalk between distinct temperature regions of the interleaved temperature profile.
Abstract:
Described herein is a glass article, for example a light guide plate, for illuminating a display panel, and in particular a light guide plate comprising a glass substrate formed by a plurality of individual segments, the plurality of glass segments arranged edge-to-edge in a two dimensional array and laminated between at least two polymer films. A display device incorporating the glass article is also described.
