The required parameters to design an imaging payload are calculated which, include integration time, optic aperture, focal length, field of view, image plane dimension, quantitative inefficiencies of detector, optic filter requirements and sampling parameters.
We find there are some sharp peaks (quantum transmissivity T = 1) in the PBG of MSPCs, and the number of sharp peaks is added with the increasing of thickness, refractive index and numbers of defect layer, which is beneficial to design the optic filter of multiple channel.
As one of the most reactive alkaline earth tungstates, BaWO4 based materials play an important role in wide variety of technological applications as light emitting diodes [8], humidity sensors [9], optic filters [10], scintillator detectors [11], photocatalysts [12], microwave dielectrics [13], phosphors [14] and solid state lasers [15].
Wavelength tunable thermo-optic filter has been designed and fabricated for 1550 nm transmission.
Light from a supercontinuum laser source is spectrally filtered to a narrow band by a rapidly-tunable acousto-optic filter, coupled into a single-mode fiber, and linearly polarized before entering the interferometer.
An integrated tunable optical filter (TOF) based on thermo-optic effect in silicon on insulator (SOI) rib waveguide is designed and simulated.
In some technological frame-works, such as Charge Routing Networks (CRNs), or fiber-optic filters, only positive state space realizations of digital signal processing algorithms, such as filters or control laws, can be implemented.
Due to the long optical wavelengths of the mid-infrared region and to the low acoustic shear wave velocities of mercury halides, the high acoustic frequency solution of the acousto-optic wave-vector diagram can be used to design new high resolution acousto-optic filters, such as reflective AOTFs and AOPDFs, which are technically impossible to realize in the UV, visible and near-infrared regions.
In this paper, we presented tunable thermo-optic filtering device based on coated silicon slab resonator with increased Q-factor for the C-band optical switching.
In this paper we propose a tunable thermo-optic filtering device based on a coated silicon slab resonator with an increased Q-factor to allow for an efficient thermo-optical switching in the C-band.
Sequential spectral scanning uses tunable bandpass filters [17], [18], liquid-crystal filters [19] or acousto-optic filters [20].
