Background Recently, light-emitting diode (LED) devices are among those mostly preferred for esthetic application because they improve the appearance of photoaged skin characterized by wrinkles, sagginess, pigmented lesions, and others. In addition,

We report on a fiber-optic transport system for next-generation wireless-communication systems utilizing 4 times 4 multiple-input multiple-output (MIMO) orthogonal-frequency-division-multiple-access (OFDMA) technology. Our system supports time-divisi

Summary from only given. We propose a new bidirectional amplification method sharing optical amplifiers and dispersion compensated fibre for the traffic in two directions. Based on our scheme, we demonstrate bidirectional 640 Gb/s transmission over 1

A novel structure of a wideband erbium-doped fiber amplifier, which includes C-band and L-band, is proposed. The signal gain is enhanced by use of the fiber reflector which reflects the L-band signal.

A dual-band erbium-doped fibre amplifier (EDFA) with high power conversion efficiency is proposed and demonstrated. The EDFA covers both the C-band around 1.55 µm and the L-band around 1.58 µm. The same signal gain can be achieved with 42% less pum
