Abstract: The present invention is directed towards systems and methods for adjusting intensity, wavelength and higher and lower frequency components of an optical signal. Photonic apparatus receives a first and a second optical signal. A waveguide provides an anomalous group velocity dispersion the first optical signal or the second optical signal and adjusts intensity or wavelength of the first optical signal or the second optical signal, in response to the anomalous group velocity dispersion.

Abstract: The invention relates to devices having periodic refractive index modulation structures and fabrication methods for the devices using a laser means. By focusing a pulsed laser beam into a transparent material substrate, a path of laser modified volumes can be formed with modified refractive index compared with the unprocessed material. By selecting appropriate laser parameters and relative scan speed, the laser modified path defines an optical waveguide. Separation distance of the individual modified volumes define a periodic modification pattern along the waveguide path, so that the waveguide structures also exhibit grating responses, for example, as spectral filters, Bragg reflectors, grating couplers, grating sensors, or other devices.

Abstract: In some variations, the present invention provides a method for forming a chip-scale photonic frequency channelizer or spectrum analyzer.

A chip-scale RF-photonic spectrum analyzer provided by this invention has extremely high resolution, such as a passband width of about 30 MHz over a free spectral range of 12 GHz, while occupying a device footprint of only about 10 cm2 area.

Abstract: High-resolution, scalable multi-touch sensing display systems and processes based on frustrated total internal reflection employ an optical waveguide that receives light, such as infrared light, that undergoes total internal reflection and an imaging sensor that detects light that escapes the optical waveguide caused by frustration of the total internal reflection due to contact by a user. The optical waveguide when fitted with a compliant surface overlay provides superior sensing performance, as well as other benefits and features. The systems and processes described provide true multi-touch (multi-input) and high-spatial and temporal resolution capability due to the continuous imaging of the frustrated total internal reflection that escapes the entire optical waveguide. Among other features and benefits, the systems and processes are scalable to large installations.

Abstract: The present application is directed towards systems and methods for efficient installation of optical and electrical cable in watercraft. A manufacturer may terminate one end of a cable in a location removed from the watercraft, allowing use of automated cable termination machines for efficiency and consistency of terminations. The single-terminated cable may then be brought to the watercraft and installed by pulling or routing the unterminated end through ductwork and pipes, watertight bulkhead throughways, and cable trays and ladders as necessary, prior to termination. Accordingly, more difficult and expensive on-site labor is reduced, and reliability is greatly increased. Furthermore, many cable tests that require termination but cannot be executed post-installation can be performed prior to installation, to ensure that at least the first termination, performed off-site, is error-free, reducing later troubleshooting and further increasing installation efficiency.
