Summary
A novel Mach-Zehnder interferometer model using coupled optical waveguides was proposed and demonstrated. This research paves the way for advanced microscale optical integrated devices.
Area of Science:
- Photonics
- Optoelectronics
- Microwave Engineering
Background:
- Mach-Zehnder interferometers (MZIs) are fundamental optical devices.
- Planar photonic crystals offer a platform for integrated optical circuits.
Purpose of the Study:
- To propose and experimentally validate a simple theoretical model of a Mach-Zehnder interferometer.
- To explore the potential of MZIs in planar photonic crystals for integrated devices.
Main Methods:
- Developed a theoretical model of an MZI using two coupled-resonator optical waveguides of differing lengths.
- Experimentally demonstrated the proposed MZI model at microwave frequencies.
Main Results:
- Achieved good agreement between the theoretical predictions and experimental outcomes.
