    摘要： A Time Domain Optical Coherence Tomography system using a modulation scheme multiplexes the scanning range of the delay line into different spectral bands. Such a modulation scheme may allow for power consumption reduction compared with a single delay line element since the same modulation pattern is being used for several channels. In an example, the optical coherence tomography system may include a plurality of stages, each stage having a group delay element. The distinct group delays may be introduced to scan a sample with distinct electrical frequency bands at distinct axial scanning depth ranges.

    摘要： A medical instrument is described that includes an optical source, an optical fiber, and a waveguide patterned upon a substrate. The optical fiber receives radiation from the optical source and includes a first segment and a second segment. The second segment is rotated about an optical axis relative to the first segment. The waveguide receives radiation from the optical source and guides a beam of radiation. The waveguide includes a first waveguide segment designed to impart a first differential group delay on the beam of radiation and a second waveguide segment designed to impart a second differential group delay on the beam of radiation. A sum of the first differential group delay and the second differential group delay is substantially zero.

    摘要： A fabrication method includes arranging a plurality of dice on a substrate and performing a first etching process that etches a first layer of the substrate at a boundary between adjacent dice on the substrate. The etching forms facets of one or more waveguides that are defined within the first layer, and the etching leaves a portion of the first layer in the boundary between the adjacent dice. The method continues with a second etching process that etches the portion of the first layer and a second layer beneath the portion of the first layer, the second etching process forming a trench in the boundary where the second layer has a different material than the first layer. The method also includes separating the dice from one another along the trench.

    摘要： Described herein are devices and methods for performing merged optical tissue evaluation and laser ablation with a catheter system that includes a processing device and a catheter with proximal and distal sections with a plurality of optical ports that are configured to transmit beams of exposure radiation to a sample, receive one or beams of scattered radiation, and transmit laser ablation energy such that a portion of the sample is ablated. The processing device includes a first optical source configured to generate a source beam of exposure radiation and a second optical source configured to generate the laser ablation energy. The catheter system further includes one or more multiplexers that direct the beams of exposure radiation to the plurality of optical ports, combine the one or more beams of scattered radiation, and direct the laser ablation energy to at least one optical port of the plurality of optical ports.
