A novel optoelectronic ferrule and easy ribbon fiber splicer for cost-effective optical interconnection

Attention has turned in recent years to optical interconnection as the most cost-effective solution to the problem of I/O bottlenecks in the wiring of conventional FR4 printed wiring boards. In this paper we propose a new configuration for the key element in realizing optical interconnections, a low-cost electrical/optical (E/O) converter module. We furthermore propose an easy splicer and a ribbonized coated-mountable fiber for multicore optical interconnections.

Reconfigurable optical add/drop multiplexer using passive temperature-compensated wavelength tunable fiber Bragg grating

A reconfigurable optical add/drop multiplexer based on a passive temperature-compensated wavelength tunable fiber Bragg grating is proposed. In the temperature range, 0-70/spl deg/C, wavelength tuning range of 8 nm and wavelength tuning accuracy of 0.05 nm was attained.

A Novel Optoelectronic Ferrule for Cost-effective Optical Interconnection Modules

We developed an optoelectronic ferrule using hoop injection molding. By mounting a vertical cavity surface emitting laser (VCSEL) (or photo diode (PD)) directly on the end-face of the ferrule, an extremely simple and cost-effective optical interconnection module can be created.

3-port WDM filter arrays based on novel planar lightwave circuit assembly technique

We propose a novel configuration of ultra-compact 1310/1490/1550-nm WDM filter arrays compounded of a thin-film filter and two planar lightwave circuits. By using simple assembly techniques to optimize the arrangement, the insertion loss less than 0.7 dB is successfully achieved.
