Feasibility Study and Standardization Activities on Radio on Fiber Devices

This paper presents the activity of feasibility study for radio on fiber (RoF) devices and systems. Also schedule of standardization process in Japan, such as national round robin test results and international round robin test plan, are described.

Integrated LiNbO3 modulator for high-speed optical quadrature phase shift keying

We investigated high-speed optical differential quadrature-shift-keying (DQPSK) modulation using an integrated LiNbO3 modulator with two sub Mach-Zehnder structures. A bias condition monitor technique was also proposed for automatic bias control in DQPSK modulation.

Standardization activities on LN modulator within IEC TC103

This paper presents the activities of a feasibility study for LiNbO3 Mach-Zehnder modulators and systems. In addition, the structure of IEC standardization, standardization activities of IEICE Japan, and international round-robin test results are described.
