摘要： The disclosed embodiments provide a system that implements an optical interface. The system includes a semiconductor chip with a silicon layer, which includes a silicon waveguide, and an interface layer (which can be comprised of SiON) disposed over the silicon layer, wherein the interface layer includes an interface waveguide. The system also includes an optical coupler that couples an optical signal from the silicon waveguide in the silicon layer to the interface waveguide in the interface layer, wherein the interface waveguide channels the optical signal in a direction parallel to a top surface of the semiconductor chip. The system additionally includes a mirror, which is oriented to reflect the optical signal from the interface waveguide in a surface-normal direction so that the optical signal exits the top surface of the semiconductor chip.

摘要： The present invention discloses a dual beamsplitting element based excimer laser pulse stretching device comprising two beam splitting elements and one confocal resonator. The first beamsplitting element splits incident laser beam into two beams, one beam enters the confocal resonator, generates a certain time delay and then is incident on the second beamsplitting element, and the second beam is directly incident on the second beamsplitting element. The second beamsplitting element further splits each of the incident laser beams into two beams, one of the two beams enters the confocal resonator, generates a certain time delay and is returned back to the first beamsplitting element to be further split, and the other of the two beams is combined with other beams which are direct outputs after being split by the beamsplitting elements or being optically delayed by the confocal resonator to form a stretched output beam. The present invention may effectively enhance the efficiency of the pulse stretching, decrease the peak power of the stretched beam, and increase the lifetime of optical elements used in the excimer laser photolithography systems.

摘要： Disclosed is a high power ultra-short pulsed laser device increasing pulse energy by using resonators. A pulsed laser device may comprise a first resonator making a pump beam resonate primarily and passing the pump beam which resonated through a first output mirror; and a second resonator comprising a first multiple reflection mirror and a second multiple reflection mirror. Also, the first multiple reflection mirror includes at least one first small area mirror, and the second multiple reflection mirror includes at least one second small area mirror, and the second resonator makes the laser beam delivered from the first resonator resonate by reflecting the laser beam repetitively. Therefore, the pulsed laser device may increase pulse energy without using a multi-stage amplifier so that a high power ultra-short pulsed laser beam can be generated.

摘要： A method for achieving high-power solid-state lasers by multiple beams combination using cascaded compound laser oscillators, comprising the following steps: 1) Designing a compound resonator to achieve an output beam perpendicular to the axis of oscillation in which a compensating lens is used; 2) Designing beam combination of two independent solid-state lasers in cascaded compound cavities and using 4f optical system to compensate the beam waist separation between two lasers; 3) Based on the first two steps, multiple beams combination of N independent solid-state lasers can be achieved. In the present invention, N output beams emitted from N independent solid-state lasers are completely combined, and the combined beams hold the same waist position, size and divergence along down the same optical axis. Therefore, it can preserve original beam quality with that of individual solid-state lasers.
