    Abstract: A method of pulsed laser processing of solid surface for enhancing surface hydrophobicity is disclosed wherein the solid surface is covered with a transparent medium during laser processing and the laser beam incidents through the covering medium and irradiates the solid surface. Two effects are obtained simultaneously. One is the laser-induced texture formation directly under the laser irradiation. The other is the deposition of the laser-removed materials along the laser scan lines. Both effects introduce surface roughness on nanometer scales, and both enhance surface hydrophobicity, rendering superhydrophobicity on the surfaces of both the laser-irradiated solid and the covering medium. Because the beam scan line spacing can be larger than a single scan line width by multiple times, this method provides a high processing speed of square inch per minute and enables large area processing.

Various embodiments are suitable for at least one of dicing, cutting, scribing, and forming features on or within a semiconductor substrate.

    Abstract: A method of forming patterns on transparent substrates using a pulsed laser is disclosed. Various embodiments include an ultrashort pulsed laser, a substrate that is transparent to the laser wavelength, and a target plate. The laser beam is guided through the transparent substrate and focused on the target surface. The target material is ablated by the laser and is deposited on the opposite substrate surface. A pattern, for example a gray scale image, is formed by scanning the laser beam relative to the target. Variations of the laser beam scan speed and scan line density control the material deposition and change the optical properties of the deposited patterns, creating a visual effect of gray scale. In some embodiments patterns may be formed on a portion of a microelectronic device during a fabrication process. In some embodiments high repetition rate picoseconds and nanosecond sources are configured to produce the patterns.

    Abstract: Embodiments described herein include a system for producing ultrashort tunable pulses based on ultra broadband OPA or OPG in nonlinear materials. The system parameters such as the nonlinear material, pump wavelengths, quasi-phase matching periods, and temperatures can be selected to utilize the intrinsic dispersion relations for such material to produce bandwidth limited or nearly bandwidth limited pulse compression. Compact high average power sources of short optical pulses tunable in the wavelength range of 1800 to 2100 nm and after frequency doubling in the wavelength range of 900 to 1050 nm can be used as a pump for the ultra broadband OPA or OPG. In certain embodiments, these short pump pulses are obtained from an Er fiber oscillator at about 1550 nm, amplified in Er fiber, Raman-shifted to 1800 to 2100 nm, stretched in a fiber stretcher, and amplified in Tm-doped fiber.

    Abstract: Examples of systems and methods for integrated photonic broadband microwave receivers and transceivers are disclosed based on integrated coherent dual optical frequency combs. In some cases, when the system is configured as a receiver, the microwave spectrum of the input signal can be sliced into several spectral segments for low-bandwidth detection and analysis. In some cases, when the system is configured as a transmitter, multiple radio frequency (RF) carriers can be generated, which can be coherently added or encoded independently for transmission of individual microwave bands. In some systems, the optics-related functionalities can be achieved via integrated optic technology, for example, based on silicon photonics, providing tremendous possibilities for mass-production with significantly reduced system footprint.
