This experimental study focuses on building a low-cost experimental VLC model consisting of ultra-bright 5 mm Light Emitting Diodes (LEDs), BPW34 silicon photodiode and TLO81CP FET Operational Amplifier (OPAMP) for a distance of 1 m at a peak data rate of 1 Mbps using On–Off Keying Non...
15. The light source of claim 10, wherein the emitter comprises a light-emitting diode (LED). 16. The light source of claim 10, wherein: the modulation scheme includes a modulation period based on an image sampling time of a rolling shutter camera of a device intended to receive the giv...
This setup allows for a multi-wavelength excitation, making use of a He–Ne laser, a diode laser emitting at 785 nm and two argon-ion lasers, one used to produce the Ultra-violet line at 364 nm and the other one for the visible wavelengths. For the detection of the Raman spectra...
Utilizing 3D-TPE-COF as coating material for WLED WLEDs have attracted extensive attention due to their wide applications in display and lighting systems55,56,57,58. A common approach to fabricate WLEDs is coating a yellow-emitting phosphor on a blue LED chip, and the white light can be pr...
Nathalie Picqué at Max-Planck-Institut für Quantenoptik and colleagues have generated tunable frequency combs in the near-infrared using a continuous-wave laser diode, a pair of electro-optic modulators and a length of nonlinear optical fibre. The combs are then converted to mid-infrared waveleng...
