A light beam scanner suitable for a scanning pulsed-laser rangefinder, which is electrically controlled without a mechanical factor, is provided, comprising an integrated laser element including a plurality of laser diodes and a light amplifier, a laser diode driving circuit, a light amplifier ...
The recent demonstration of multilayer heterogeneous integration provides a practical solution and enabled the first-generation of lasers fully integrated with SiN waveguides. However a laser with high device yield and high output power at telecommunication wavelengths, where photonics applications are ...
8. Specifically, a polarization-maintaining fiber from a pigtailed laser source (OBIS-LX-FP-637 100 mW, Coherent, Inc.) was connected to a collimator (Thorlabs, TC06APC-633). The collimated light was projected onto a doublet achromatic lens (Thorlabs, APC125-75) and then directed to a ...
is external to the laser30,31,32,33,34or optical pumping35,36,37,38,39. This limitation is more severe at short wavelength below silicon’s bandgap wavelength, where currently only thermal tuning can be used for external cavities of integrated lasers. As an example, in atomic physics, where...
A hybrid-integrated laser/driver module for 10 Gbit/s optical transmission has been developed. A 1.55 mu m DFB laser and a driver hybrid IC (HIC) are integrated with an optical isolator in the module package. The module has a novel structure which uses a coplanar line HIC consisting of ...
The waveguide directs energy from the laser toward the media. The optical power monitor is optically coupled with the waveguide. The optical power monitor for captures a portion of the energy, converts the portion of the energy to heat and measures a local temperature proximate to the optical ...
Frequency modulated continuous wave laser ranging (FMCW LiDAR) enables distance mapping with simultaneous position and velocity information, is immune to stray light, can achieve long range, operate in the eye-safe region of 1550 nm and achieve high s
High-speed (10 Gbit/s) and low-drive-voltage (1 V peak to peak) InGaAs/InGaAsP MQW electroabsorption-modulator integrated DFB laser with semi-insulating bu... An MQW electroabsorption-modulator integrated DFB laser fabricated by using the in-plane bandgap energy control technique and a low-...
The aim of this phantom study was to compare the accuracy, speed and technical performance of CT guided needle placement using the conventional technique versus a workflow utilizing the novel, gantry integrated 3D laser guidance system for both an expert and a novice user. Our hypothesis is that...
