Abstract: A keyless synthesizer t can stimulate all three senses (hearing, muscle movement and visual) at once in patients born with C.H.A.R.G.E. syndrome while they play and, at the same time, enjoy and have fun with the device. A keyless synthesizer operational by a single hand of the user includes an ultrasound range sensor responsive to the distance “d” of a user's hand from the sensor for generating a sensor signal corresponding to the distance “d”. A programmable microcontroller programmed to convert the sensor signal to one of a plurality of discrete signals. A synthesizer is responsive to each discrete signal for generating a discrete tone. A multi-color generator is responsive to each discrete signal for generating a discrete color so that for each discrete signal corresponding to a distance “d” both a discreet tone and an associated discreet color are generated.

Abstract: A continuous optical beat laser element for generating terahertz (THz) waves and a laser source using same includes periodically poled lithium niobate (ppLN) crystals arranged along a predetermined direction forming a surface generally parallel to the predetermined direction. A Ti diffused region is applied on the surface and an array of gold nanowires are applied on the Ti diffused region to form a gold metal-insulator-metal (MIM) element that optimizes coupling and channeling of THz radiation from the crystals into the gold nanowires. The system provides a simple, stable, compact and cost-effective THz source using a widely tunable C-band SOA-based laser to excite a non-linear photo-mixer to produce terahertz radiation that ranges from 0.8 to 2.51 THz at room temperature. This laser source can be modified into an all fiber-based THz generator by embedding ppLN crystals in a fiber filament configuration resulting in less absorption and producing high output power.

Abstract: A dual output semiconductor optical amplifier-based tunable fiber laser is provided that can be switched from low to high power and vice versa. The laser system uses bidirectional semiconductor optical amplifier (SOA) for amplification and hence is able to introduce a unique feature of adjustable dual/single output ports.
