    摘要: An apparatus and method using an array of VCSELs operable to emit light at one or more wavelengths, pulse-repetition rates, pulse durations, pulse powers, pulse energies, and/or light-distribution spatial and/or temporal patterns, that are effective to stimulate or photostimulate human or other animal tissue, and in particular, nerve tissue. In some embodiments, the invention provides an implantable device that includes an array having a plurality of VCSELs in a spatial pattern suitable to stimulate or photostimulate a plurality of different areas of tissue (e.g., a plurality of different nerves). In some embodiments, the device is instead partially implantable. In some embodiments, the device is instead external to the body of the animal.

    摘要: An integrated photonic apparatus that includes a glass substrate having a major surface, a first waveguide segment and a second waveguide segment, and a folded evanescent coupler connecting the first waveguide segment to the second. The folded evanescent coupler is formed by a first length of the first waveguide segment and an equivalent length portion of the second waveguide running parallel and adjacent to the first waveguide segment. The first length is substantially equal to one half of an evanescent-coupler length needed to transfer a first wavelength in a non-folded evanescent coupler. A reflector (e.g., dielectric mirror that is highly reflective to light of the first wavelength and also highly transmissive to light of a second wavelength) is located at an end of the folded evanescent coupler. The first length is selected to transfer substantially all light of a first wavelength.

    摘要: A modulating optical element having ports wherein either port can output or receive light signals. An electrooptic effect is applied to the optical element to allow the light signals to pass or not pass through the optical element. Due to the electrooptic effect in preventing signals from passing through the optic element, light signals radiate out of the optical element and are absorbed by the substrate of the optical element assembly. Rather than being lost, the energy from the light signal is converted to current which may be used for other purposes in the modulator system, such as bias stabilization.

    摘要: An apparatus and process using a high-power, short-pulsed thulium laser to output infrared laser pulses delivered through an optical fiber, for cutting and ablating biological tissue. In some embodiments, the pulse length is shortened sufficiently to keep inside the stress-confined ablation region of operation. In some embodiments, the pulse is shortened to near the stress-confined ablation region of operation, while being slightly in the thermal-constrained region of operation. In some embodiments, the laser is coupled to a small low —OH optical fiber (˜100 μm diameter). In some embodiments, the device has a pulse duration of about 100 ns for efficient ablation; however in some embodiments, this parameter is adjustable.
