Recent research progress on single sideband modulator
Rofea Optoelectronics to lead the global single sideband modulator market. As the world's leading manufacturer of electro-optic modulators, Rofea Optoelectronics' SSB modulators are praised for their superior performance and application flexibility. Newly launched 5G and 6G communication systems have increased demand for high-speed modulators, and the SSB modulators are ideal for these new systems due to their high speed and low insertion loss characteristics.
In the field of optical fiber sensing, LFMCW LiDAR systems with SSB modulators show excellent performance in nondestructive testing and remote sensing applications. This kind of system has high precision and high resolution, can provide accurate distance and speed measurement, so it has a wide range of applications in aerospace, unmanned vehicles, intelligent transportation systems and other fields.
In the field of scientific research, SSB modulators are used in a variety of cutting-edge research projects, such as quantum computing, ultrafast optics, spectroscopy, etc. Its high operating bandwidth and stable output optical signal provide an ideal test environment for these projects.
In the emerging biomedical field, SSB modulators are also being used to develop new optical imaging and detection techniques. For example, multi-photon microscopy using SSB modulators can provide high-resolution and high-definition imaging of biological tissues, which has important implications for clinical diagnosis and therapy. In these areas, as technology continues to evolve, it is reasonable to believe that there will be more innovations and breakthroughs in the future.

SSB series suppressed carrier SSB modulation unit is a highly integrated product with independent intellectual property rights of Rofea Optoelectronics. It integrates high-performance dual-parallel electro-optic modulator, microwave amplifier, adjustable phase shifter and bias control circuit to realize optical SSB modulation output. Its performance is reliable, easy to use, and it has a wide range of applications in microwave photonics and optical fiber sensing systems.
In structure, the SSB modulator uses Mach-Zehnder modulator, bias controller, RF driver, phase shifter and other necessary components integrated into one. This design greatly simplifies the use process and increases the reliability of the system. Its characteristics of low insertion loss, high working bandwidth and stable output optical signal make it have wide application prospect in scientific research field.
