Abstract: Tuning parameters of individual wavelength channels transmitted over a multimode optical fiber is provided. Characteristics of the multimode optical fiber used for an optical data link within an optical signal transmission system are retrieved. A wavelength channel grid including each central wavelength in a plurality of central wavelengths that corresponds to each particular wavelength channel in a plurality of wavelength channels used to transmit data via optical signals over the multimode optical fiber is determined. A maximum allowable data rate is calculated for each wavelength channel based on the characteristics of the multimode optical fiber at defined channel wavelengths, optical signal transceiver specifications, and data transmission performance requirements for the optical signal transmission system. Operational parameters are assigned to each wavelength channel based on the calculated maximum allowable data rate for each wavelength channel to achieve the data transmission performance requirements for the optical signal transmission system.

Abstract: A method of manufacturing a glass substrate to control the fragmentation characteristics by etching and filling trenches in the glass substrate is disclosed. An etching pattern may be determined. The etching pattern may outline where trenches will be etched into a surface of the glass substrate. The etching pattern may be configured so that the glass substrate, when fractured, has a smaller fragmentation size than chemically strengthened glass that has not been etched. A mask may be created in accordance with the etching pattern, and the mask may be applied to a surface of the glass substrate. The surface of the glass substrate may then be etched to create trenches. A filler material may be deposited into the trenches.

Abstract: Aspects of the invention are directed to a method for forming an optical waveguide structure. Initially, a base film stack is received with an optical waveguide feature covered by a lower dielectric layer. An etch stop feature is then formed on the lower dielectric layer, and an upper dielectric layer is formed over the etch stop feature. Subsequently, a trench is patterned in the upper dielectric layer and the etch stop feature at least in part by utilizing the etch stop feature as an etch stop. Lastly, a waveguide coupler feature is formed in the trench, at least a portion of the waveguide coupler feature having a refractive index higher than the lower dielectric layer and the upper dielectric layer. The waveguide coupler feature is positioned over at least a portion of the optical waveguide feature but is separated from the optical waveguide feature by a portion of the lower dielectric layer.

Abstract: Methods an systems for low-power transmission include biasing an emitter in a non-linear operating range of the emitter near a threshold current of the emitter. A data signal is distorted to add a precursor pulse to a rising edge of a data waveform to quickly bring the emitter into a linear operating range. The distorted data signal is transmitted at the emitter.
