A 1-by-2 compact injection-based switch is reported utilizing interior-ridge ring resonators, demonstrating nanosecond-scale switching speed, single-mode, low-loss (0/1.3dB for thru/drop port) with efficient integrated thermal tuner (7.25μW/GHz). OCIS codes: (130.4815) Optical switching devices; (130.3120) Integrated optics devices; (200.6715) Switching.
We have experimentally investigated single-port injection-triggered switching in a new class of semiconductor ring lasers with integrated gain, phase and passive waveguide sections as a building-block for all-optical signal processing such as high-speed analog-to-digital conversion. ©2009 Optical Society of America OCIS codes: (250.3140) Integrated optoelectronic circuits; (140.3560) Lasers, ring
A simple analysis is presented of twin-stripe semiconductor Y-junction laser amplifier switches that operate through simultaneous changes in gain and refractive index due to free carrier injection. This shows that (in contrast to four-port directional coupler devices based on the same mechnism) good cross-talk performance may be obtained for a wide range of operating conditions.
The number of injector holes and the fuel-injection pressure in an internal combustion engine can affect performance exhaust emissions. Conversion a port-injection gasoline to HCNG direct-injection improves In addition, increasing injection helps increase performance. this study, AVL Fire software was used perform simulation by certain adjustments. applied mods 15, 20, 25 bars, numbers were 3 6...
Quantum measurement of amplitude fluctuation is performed by the injection of 2.5-dB amplitude-squeezed light produced by a quantum-well laser into the dark port of a beam splitter as the meter wave. It is shown that the measurements satisfy the criteria of quantum nondemolition measurement. The measured transfer coefficient and the quantum-state preparation ability are 1.07 and 0.8, respectively.
We demonstrated a 1 4 all-optical packet switch with all-optical header processing at a header rate of 5 Gb/s and payload rate of 10 Gb/s using injection-locking in a single Fabry–Pérot laser diode at each output port of the switch.
The use of totally implantable venous access devices in radiology may be associated with complications such as occlusion of the system (because of the high density of some contrast), infection (if the port is not handled in aseptic conditions, using proper barrier protections), and mechanical complications due to the high-pressure administration of contrast by automatic injectors (so-called pow...
93 [1]. Unlike permanent devices that have to be implanted surgically under general anesthesia, percutaneous catheter-ports may be installed under local anesthesia, a benefit for the many cancer patients who have already undergone cancer surgery. The subclavian route is also an option; however, there exists a risk of pneumothorax, reported to be around 4%, and also other complications such as l...
