In this article, new relations between ternary helix and Reed-Muller transforms have been analyzed. In addition, the new converting matrices and corresponding hardware implementations in Galois Field (3) that can convert directly between ternary helix and Reed-Muller spectra have also been presented.
A coarse wavelength-division multiplexing (CWDM) bidirectional transceiver was demonstrated by tuning transmission band of thin-film filter (TFF) based on the relation between tilted, rotated and ferrule angles of optical fiber. The packaging of the module was designed for keeping the transmission band with spectral bandwidth of 10nm by adjusting incident angle of the excited light to TFF. As a result, the fabricated module showed transmitter output power of 0.26dBm under the injection current of 30mA and receiver sensitivity of -22.5dBm at the error rate of 10-12 under 2.5Gbps full duplex operation.
We report the design, fabrication and electromechanical performance of a newly developed micro electromechanical XY-scanner for micro-optical spatial light modulation using the silicon micromachining technology. A two-dimensional stage is integrated with a silicon micro lens to scan a transmitting infrared light of 1.55-micron-wavelength by the mechanism of the ƒ-θ lens scanner. Mechanical displacement of up to ± 10 microns (optical angle of ± 0.57 degrees) was obtained with a drive voltage of 30V; optical simulation has suggested that the scanner can be used to construct a free-space optical crossconnect of 9-input by 9-output port counts.
