چکیده
We present the design of a short broadband fiber directional coupler for terahertz (THz) radiation and demonstrate a 3 dB coupler with a bandwidth of 0.6 THz centered at 1.4 THz. The broadband coupling is achieved by mechanically downdoping the cores of a dual-core photonic crystal fiber by microstructuring the cores. This is equivalent to chemical downdoping but is easier to realize experimentally.

Design and optimization of mechanically down-doped terahertz fiber directional couplers.
We present a thorough practical design optimization of broadband low loss, terahertz (THz) photonic crystal fiber directional couplers in which the two cores are mechanically down-doped with a triangular array of air holes. A figure of merit taking both the 3-dB bandwidth and loss of the coupler into account, is used for optimization of the structure parameters, given by the diameter and pitch ...
متن کاملA Study of Broadband Microwave Fiber Optic Links with Linearized Integrated-Optic Modulators
A universally accepted figure of merit for analog microwave transmission links is the spur-free dynamic range (SFDR), which is the ratio (usually expressed in dB) of the largest to smallest signal a link can transmit and receive without introducing any measurable distortion. This paper presents the result of a study of broadband, microwave fiber optic links that contain high-linearity integrate...
متن کاملRouted Wavelength WDM Networks
An optical fiber can potentially have more than 30 THz of bandwidth that can be exploited by future generation broadband ISDN networks. However, because of the mismatch between optical transmission and electronic processing, the network transmission rate cannot exceed few Gbps. One popular solution to this problem is to employ wavelength division multiplexing (WDM) by fragmenting the whole band...
متن کاملUltra-broadband High Coupling Efficiency Fiber-to-Waveguide Coupler Using Si3N4/SiO2 Waveguides On Silicon
An easy-to-fabricate but very efficient fiber-to-waveguide coupler is theoretically analyzed and experimentally demonstrated. In this design, light from a single-mode fiber can be butt-coupled into a single-mode high-index-contrast Si3N4/SiO2 waveguide with a measured coupling efficiency of 96 % at the wavelength of 1550 nm, and > 90 % in the spectral range from 1450 nm to 1650 nm. Large horizo...
متن کاملTerahertz-bandwidth photonic temporal differentiator based on a silicon-on-isolator directional coupler.
We experimentally demonstrate a terahertz-bandwidth photonic differentiator employing a silicon-on-insulator directional coupler. The integrated waveguide coupler with two identical paralleled strip waveguides achieves a first-order differentiator when full energy coupling is met from one waveguide to another. The integrated waveguide coupler can offer different operation bandwidths by changing...
