چکیده

To detect chemicals, we proposed a photonic crystal fiber (PCF) with hexagonal cladding and hexahedron core (THz). Circular air holes (CAHs) in the vestibule provide basis of suggested sensor. develop evaluate our PCF sensor, employed finite element (FEM) technique perfectly matched layers (PML), which utilized optical parameters numerically. Here, 92.65%, 95.25%, 90.70% are relatively sensitive, confining losses low. The value 5.40 × 10?08, 6.70 10?08 dB/m, 5.75 dB/m for three chemicals such as Ethanol (n = 1.354), Benzene 1.366) Water 1.330) effective material loss (EML) 0.00694 cm?1. Hx-PCF sensor has been successfully tested at 1 THz. We certain that sensor's optimal geometric structure can be manufactured it contribute to real-world applications biomedicine industry. In terahertz areas, is also suited wide range medical signals

Terahertz wave transmission in flexible polystyrene-lined hollow metallic waveguides for the 2.5-5 THz band.

A low-loss and low-dispersive optical-fiber-like hybrid HE₁₁ mode is developed within a wide band in metallic hollow waveguides if their inner walls are coated with a thin dielectric layer. We investigate terahertz (THz) transmission losses from 0.5 to 5.5 THz and bending losses at 2.85 THz in a polystyrene-lined silver waveguides with core diameters small enough (1 mm) to minimize the number o...

A Study on Narrow-band THz (Terahertz) Source with Adjustable Center Frequency Based on Optical Rectification

The center frequency of the narrow-band THz wave is always unstable with the optical rectification methods. Therefore, the high-phase stable time-delay generator Etalon and the parallel grating pair compressor with the self-adaptive optical path compensation function are designed according to the principle that two lasers in different paths will result in specific relative time delay; with LiNb...

Optical Modelling using Gaussian Beam Modes for the Terahertz Band

Special approaches unique to the waveband are required for the modelling of terahertz optical systems. Ray tracing is inadequate because in typical instruments the propagating beams are not very many wavelengths in diameter and a "quasi-optical" approach is required in which Fresnel diffraction effects can be efficiently and accurately simulated. Typically, it is also necessary to be able to si...

Metamaterial Devices for the Terahertz Band

Terahertz (THz) and metamaterials are both hot topics in electromagnetics research. The THz band (0.1-10 THz) lies in the ‘gap’ between microwave and far infrared regions. Research is currently underway to characterize how these waves interact with matter, with potential applications including security screening, medical imaging, and non-destructive evaluation. Metamaterials are artificial mate...

Fiber-based, hybrid terahertz spectrometer using dual fiber combs.

We constructed a fiber-based, hybrid terahertz (THz) spectrometer having two working modes, asynchronous-optical-sampling THz time-domain spectroscopy (AOS-THz-TDS) and multiple-frequency-heterodyning THz comb spectroscopy (MFH-THz-CS), by use of dual fiber-laser-based frequency combs. A spectral range of 2THz and dynamic range of 100 was achieved at the single sweep measurement of 200ms in the...
