A novel fabrication method of tilted microlens array for light control films is developed to increase the efficiency of a liquid crystal display that can collect lateral light sources and improve the dazzling problem within the angle of view. Initially, the pattern allows UV exposure by placing a photoresist-coated substrate on an inclined fixture. An inclined photoresist column array is made with...
In this paper we present an in-home optical network infrastructure based on 1 mm core diameter graded-index plastic optical fibre. A combined transmission of a multi-gigabit baseband data stream, based on discrete multitone modulation, and a radio frequency signal, based on ultra wideband technology, is shown. A detailed experimental study on the performance of the two types of signals in the combined...
Recent activity to achieve multi-gigabit transmission over 1 mm core diameter graded-index and step-index plastic optical fibers for distances up to 50 meters is reported in this paper. By employing a simple intensity-modulated direct-detection system with pulse amplitude or digital multi-tone modulation techniques, low-cost transceivers and easy to install large-core POFs, it is demonstrated that...
We report multi-Gbit/s capacity in 1-mm diameter graded index plastic optical fiber exploiting low-cost eye safe compliant transceivers. Transmission rates between 5.3 and 7.6 Gbit/s are achieved for lengths between 10 and 50 m using DMT.
We report, for the first time, 4.7 Gbit/s transmission over 50 m long 1 mm diameter multi-core step-index plastic optical fiber, employing discrete multitone techniques and low-cost optical transceiver. A spectral efficiency of 13 bit/s/Hz is demonstrated.
We demonstrate a novel technique for generation and transmission of IR-UWB signals over 100-m 50-mum core GI-POF. IR-UWB pulses are made by linearly combining two first-order derivatives of Gaussian pulses with different pulse-shaping factors.
We demonstrate a novel technique for generation and transmission of IR-UWB signals over 100 metres 50-mum core GI-POF. IR-UWB pulses are made by linearly combining two 3rd-order derivatives of Gaussian pulses with different pulse-shaping factors.
