    摘要: A laser projection system including a projection screen and a laser projector is revealed. The projection screen includes at least one light emitting layer having at least one luminescent material that is excited by excitation light with a specific wavelength range to generate excited light with another wavelength range. The laser projector consists of a laser light source module, a laser signal modulation module, a rotation plane mirror module, a rotation plane mirror control module, and a signal conversion module. The laser projector produces excitation laser according to an image signal of a static image or dynamic image and projects the laser to the projection screen correspondingly for an image displayed. Thus a projected image with high recognition is displayed on the projection screen in a transparent manner in natural sunlight. Therefore efficiency and application of the laser projection are improved.

    摘要: A display device is revealed. The display device includes a laser source for emitting a laser beam, a pre-optics for processing the laser beam, a light scan member such as a MEMS mirror for converting the processed laser beam into a scanning light beam, and/or a corresponding post-optics. A switch-control beam splitter is disposed on the light path of the laser beam, after the light scan member so as to divide the scanning light beam into a reflected light beam and a transmitted light beam. They are two different light paths and generate a virtual image as well as a real image respectively.

    摘要: An improved gain-clamped optical amplifier is disclosed. A series of laser cavities are placed along the amplifier axis. The laser cavities are designed such that the carrier densities of the amplifier decline toward the signal output end. Since the gain clamping amplitudes at positions along the amplifier can be different, we have the freedom to optimize the optical gain at all location, to minimize the noise impact at the signal input end, and to maximize the saturation output power at the signal output end. In addition, carrier levering effect realized by gain/loss wings further lowers the noise figure, and extends the optical gain and saturation output power. An ideal optical amplifier with high linear gain, small noise figure, and large saturation output power and extended dynamic range is then achieved. Energy saving is the bonus of using the invented amplifiers.

    摘要: A unitary two-section semiconductor optical amplifier including a first active region, a second active region, and a passive region integrally connected between the first and second active regions to minimize optical loss therebetween. The arrangement of the two-section semiconductor optical amplifier is advantageous in that the gain in the first active region may be increased in order to maintain a substantially constant input power level to the second active region over a relatively wide dynamic range of input power levels to the first active region.

    摘要: An optical coupling system couples an optical fiber to an optical semiconductor device. A beam expander is disposed within the optical semiconductor so as to receive light from or transmit light into the optical fiber. The coupling is accomplished by disposing a layer of an index matching gel or epoxy on either surface of the semiconductor optical device or the end portion of the optical fiber and another layer of an antireflective material adjacent to the index matching gel or epoxy. The semiconductor device may include an array of optical devices, each coupled to a corresponding optical fiber via the arrangement that comprises the index matching gel and the antireflective material. The semiconductor device may also include an array of waveguides, each configured to receive light from a corresponding optical fiber.
