Abstract: A thermo-optic switch using a small drive power while exhibiting a reduction in the coupling loss caused by the coupling to optical fibers and a switch speed of several hundred microseconds or less. A method for manufacturing the thermo-optic switch and a method for changing an optical line switching using the thermo-optic switch are also disclosed. The thermo-optic switch includes a substrate having etched portions at regions respectively corresponding to input and output terminals of the thermo-optic switch, a lower clad layer formed over the substrate, the lower clad layer having an input taper formed at the region corresponding to the input terminal and adapted to convert a circular mode, input from an optical fiber connected to the input terminal, into an oval mode having a rib shape, and an output taper formed at the region corresponding to the output terminal and adapted to convert the oval mode into a circular mode allowed to be input to an optical fiber connected to the output terminal, a core layer formed over the lower clad layer and provided with branched waveguides having a rib structure, the branched waveguides selectively receiving the oval mode from the input taper and outputting the received oval mode to the output taper, an upper clad layer formed over the core layer, and switching electrodes formed on the upper clad layer and selectively activated to apply heat to an associated one of the branched waveguides in such a fashion that an effective refractive index difference occurs between the branched waveguides, thereby causing the branched waveguides to selectively receive the oval mode from the input taper.

Abstract: An erbium doped fiber amplifier has a shape of the gain spectrum which is independent of the operating conditions by using a gain medium with this property. The gain medium can be an erbium-doped fiber with a wavelength-independent gain swing over a range of wavelengths (especially a low Al.sup.3+ -content aluminogermanosilicate EDF). As an alternative, the gain medium can consist of at least two pieces of EDFs, so that changes of the shape of the gain spectra (induced by changes of the operating conditions) in the different types of EDFs effectively offset each other. Within an overlapping wavelength range, the gain spectrum can then be further modified in a power-independent way (i.e.--independent of operating conditions) so as to make the gain spectrum flat (i.e.--gain wavelength-independent) by means of one or several optical filter(s) placed before and/or after the gain medium, and/or distributed along the gain medium, or by means of a "filtering EDF", specially selected in a constant population inversion region of the EDFA. The gain spectrum thus obtained is both flat and independent of operating conditions so that a dynamic gain flatness which is independent of input signal power, operating gain, and population inversion is realized. As a desired consequence of the dynamic gain flatness, the gain of different channels in a WDM system will always be equal, irrespective of the operating conditions. Furthermore, AC gain tilt will be eliminated for analog AM CATV systems.

Abstract: A backlight assembly includes a light source, a light-guide plate and an integrally formed frame. The light-guide plate guides light generated from the light source. The integrally formed frame includes a chassis and a mold frame integrally combined with the chassis as an indivisible unitary element through insert/outsert injection. The integrally formed frame receives the light source and the light-guide plate. A hemming part is formed on a sidewall of the chassis to increase strength of the integrally formed frame. Therefore, the number of elements is decreased, and strength against bending stress, impact resistance and heat dissipation are improved.

Abstract: A backlight assembly includes at least one U-shaped lamp, a first connecting member, and a second connecting member. The U-shaped lamp includes a U-shaped lamp tube, a first external electrode covering a first end portion of the U-shaped lamp tube, and a second external electrode covering a second end portion of the U-shaped lamp tube. The U-shaped lamp tube generates light when a first driving voltage is applied to the first external electrode and a second driving voltage is applied to the second external electrode. The first connecting member is electrically connected to the first external electrode for applying the first driving voltage to the first external electrode. The second connecting member is electrically connected to the second external electrode for applying the second driving voltage to the second external electrode. Therefore, interference between a wire for applying power to the U-shaped lamp and the U-shaped lamp is reduced.
