Special Issue Information

Dear Colleagues,

Optical modulation, which encodes the high-speed baseband signal onto the optical carrier with high signal fidelity, is indispensable for every level of optical networks. Innovative modulator technologies are the core of optical modulation in optical communication networks, always pursuing higher capacity and lower power. The ideal modulator should feature low power consumption, large bandwidth, low loss, high linearity, a compact footprint, and low manufacturing cost. It is well-known that device structure, design, material platforms, fabrication processes, package technology, and transmission systems all have a critical impact on modulation performance. Therefore, we focus attention on these factors and push optical modulation towards a next-generation electro-optic interface, both in intensity modulation direct detection or coherent optical transmission systems.

We are pleased to invite you to contribute an original research article or review to this Special Issue of Photonics, entitled “Optical Modulation”. This Special Issue aims to collect the latest experimental and theoretical (simulation) advancements in integrated, bulk, or free-space-type devices and subsystems for high-speed and low-power optical modulation.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following: electro-optic modulator, electro-absorption modulator, integrated modulator, spatial light modulator, electro-optic frequency comb, intensity modulation direct detection transmission, coherent optical transmission, and transmitter.

We look forward to receiving your contributions.

Today, the task of developing microoptical gyroscopes is topical. Usually, tunable lasers with a built-in frequency stabilization system are used in such gyroscopes. They are comparatively bulky, which hinders the real miniaturization of optical gyroscopes. We propose a new approach implemented by using a Mach–Zehnder modulator with a passive ring resonator connected to one of its arms. This makes it possible to obtain a mutual configuration and makes the use of a tunable laser optional. Two ring resonators made of the polarization-maintaining fiber, suitable for use as sensitive elements of a gyroscope, were realized and investigated. Their Q-factor is equal to 14.5 × 106 and 28.9 × 106. The maximum sensitivity of the proposed method when using the described resonators is 3.2 and 1.8 °/h, respectively. The first experimental setup of a resonator gyroscope implementing this approach has been manufactured and analyzed. When measuring the rotation speed by the quasi-harmonic signal span and its phase, the measurement accuracy was approximately 11 and 0.4 °/s, respectively. Full article
