Abstract:We propose a low cost polymeric optical waveguides-based optical CDMA encoder and decoder modules. The structures of the optical CDMA encoder and decoder modules are presented. The performance of the optical CDMA encoder and decoder modules is simulated using 10-chip binary phase-shift keying (BPSK) coding schemes. The optical CDMA encoder and decoder modules can effectively transmit and recover optical CDMA data streams. The SNR of the received signal is analyzed and determined to be primarily from the cross correlation with other channels.

“…Thus, a TIR optical switch can be formed if a heater is set at the crossing point of a symmetric X junction. 17,18,19 Compared with various TO switch configurations, such as a digital optical switch (DOS) 20 , a MachZehnder interferometer (MZI) switch 21 , or a directional coupler switch 22 , TIR switches have a significant advantage in their broad optical bandwidth (or equivalently, their wavelength insensitivity). Fig 6 shows the schematic diagram of a 2 x 2 TO TIR switch.…”

A 4-bit polymer optoelectronic true time delay device is demonstrated. The device is composed of monolithically integrated, low loss, passive polymer waveguide delay lines and 2x2 polymer thermo-optic switches. Waveguide junction offsets and air trenches simultaneously reduce the bending loss and device area. Simulations are used to optimize the trench and offset structures for fabrication. The 16 time delays generated by the device are measured to range from 0 to 177 ps in 11.8 ps increments. The packaged device has an insertion loss of 14.5 dB and the delay switching speed is 2 ms. The delays generated by the device are suitable for steering a 1D or 2D sub-array of an X-band phased array antenna system.

Abstract:We propose a novel hollow waveguide optical switch composed of a multi-mode interference (MMI) coupler with a variable air core. The numerical simulation of the proposed optical switch is carried out for investigating switch performances. Switching operation can be obtained by mechanical displacement of the air core of an MMI hollow waveguide. A hollow waveguide consists of Ta 2 O 5 /SiO 2 multilayer mirrors for optical confinement. The result shows a possibility of switching of about 99.5% optical power fraction with a switching length of 500 µm and a small displacement (∆D core = 2.5 µm) of an air core thickness.
