“…Another type of filter, the MZF, which is described in Appendix A, is used as an optical filter and an intensity modulator in optical communication applications [13][14][15]. Although the PBF and the MZF have been developed separately in the respective fields, the basic structure and the operating principle of the MZF can be thought of as being similar to those of the PBF [16,17].…”

Abstract-The present paper describes the feasibility of the FDM system using Mach-Zehnder filters for a power control system in a smart grid. The interconnection of large quantities of the distributed power sources, such as PV power sources, to the current bulk power grids is anticipated, and as a result, fluctuations of voltage and frequency will increase and make the adjustment of the power demand-supply balance difficult. By applying information communication technology to a power supply system in order to control the digital grid routers, energy-savings, and a stable power supply, the widespread use of renewable energy is expected. The digital grid cell includes numerous consumers, such as houses, office buildings and factories, which may or may not have PV power sources. The proposed FDM system enables the processing of a great deal of information to be exchanged incoherently between consumers and power generators, because the FDM system has the capability of 2 N transmission channels and the transfer functions of which can be expressed as the basis of the plain representation of the transfer function of the Mach-Zehnder filter. Using the FDM system, it will be possible to control a power supply system in a smart grid in order to maintain a stable power supply, energy savings, and a suitable adjustment of the power demand-supply balance.

“…There are many optical coherent communication systems have been demonstrated in the literatures [1][2][3][4][5][6][7][8][9][10]. The modulation technique in the non-coherent optical communication system is based on the direct intensity modulation (IM) to the laser diode, and the transmitted signal is placed on the output intensity of the laser diode, thus the linewidth of the laser diode is not the critical parameter in this system.…”

A new optical communication system named as the pseudo-PM (phase modulation) optical communication system has been demonstrated. In this system, the PM-signal is generated by applying a triangular waveform to the laser diode and followed by an optical fiber based Mach-Zehnder interferometer. The linewidth requirement of the laser diode in our system is much less critical thanthe coherent optical-PM system.
