Let a(k) be the characteristic of the optical filter in terms of an angular wavenumber k.
The receiver optical filter has a 0.16 nm bandwidth and the APD receiver has a baseline sensitivity of -33 dBm at 2.3 Gbit/s.
We investigate in detail the consequences of the optical filters and mismatch of emission spectra and extinction coefficients.
The ramp also tunes the optical filter so that its resonant wavelength is proportional to the ramp voltage.
ITAR registered and ISO 9001:2008 compliant, DSI's highly durable optical filters provide zero-shift capabilities in the ultraviolet (UV), visible, near-infrared (NIR), shortwave infrared (SWIR), midwave-IR (MWIR), longwave IR (LWIR) and very longwave IR (VLWIR).
In this paper authors have measured amplitude transfer functions of fibre Bragg grating (FBG) technology optical filters with 50 GHz and 100 GHz full width half maximum (FWHM) bandwidth and have evaluated their performance in 2.5 Gbit/s and 10 Gbit/s DWDM direct transmission system over a typical length of broadband access network.
This describes the use of a matched optical filter for the holographic storage of biometric data, such as a fingerprint, the capture device and the correlation device for reading the fingerprint and checking against the stored, filtered image.
The transfer standard is an erbium-doped fiber amplifier that is coupled to a linear polarizer and a narrow-band optical filter centered in the 1550 nm wavelength range.
As there are no holographic materials sensitive to IR light, the key can be protected against copying by tuning it to reconstruct at IR wavelengths and also by using an optical filter to cut the UV and visible light.
The ficon TEC[R] Filter Master from AMS Technologies is an approach to full or half automated optical filter substrate mapping, designed to meet the needs of high and medium volume production.
The transfer standard is an erbium-doped fiber amplifier to which is coupled a linear polarizer and a narrow-band optical filter ([less than]5 nm) centered in the 1550 nm wavelength range.
