Communication demand is paramount for disaster-affected people to confirm safety, seek help, and gather evacuation information. However, the communication infrastructure is likely to be crippled due to a natural disaster, which makes disaster respons

In this paper, we show the influence of intrachannel crosstalk in an optical switch network. The intrachannel crosstalk is mainly due to a signal that is not sufficiently blocked by the optical switch. The signal has a broadband spectrum and causes c

This paper describes a phase-locked multicarrier light source that employs a continuous wave (CW) light source, two phase modulators, and a dispersion medium. A sinusoidal phase modulation (PM) with a modulation index of ?/4 and a group velocity disp

This paper describes an adaptive dispersion equalizer (ADE) that uses an asynchronous dispersion-induced chirp monitor and the detailed study of the first demonstration of 160-Gb/s adaptive dispersion equalization. The device successfully equalized t

In this paper, the characteristics of a fiber Bragg grating fabricated with a chirped phase mask are compared with those of a fiber Bragg grating that is made chirped by addition of distortion to a uniform fiber Bragg grating without phase error. It

We demonstrate a 100 Gbit/s real-time digital coherent transmission over a 32-km GI-MMF with a 62.5 μm core diameter. The DSP enables the optical channel to be switched from SMF to GIF within 70 ms.

We realized a wavelength tunable optical filter based on a fiber Bragg grating using multilayer piezoelectric transducers (MLP). The Bragg wavelength of the filter can be easily tuned in proportion to an applied low DC voltage. The tuning range effic
