The new indium phosphide modulator achieves unprecedented data transfer rates.
With the rapid growth of data traffic, there is an urgent need for compact optical transmitters and receivers that can handle multi-level modulation formats and achieve extremely high data transfer rates.
An important step towards implementing this requirement was the development of a new miniature coherent modulator driver (CDM) based on indium phosphide (InP). Scientists have demonstrated that it outperforms other similar devices in terms of maximum baud rate and bandwidth per wavelength.
CDM-optical transmitters used in optical communication systems for superimposing information on the luminous flux by modulating the amplitude and phase before transmitting via optical fiber.
Improving data transmission is essential as services that require high data throughput, such as video distribution and web conferencing, are becoming more common. It is noted that for the implementation of new services and convenient services, it is extremely important to increase the overall data transfer rate in optical transmission systems. The development of an optical transmitter that covers both the C-and L-bands in one module allows flexible network management and reduces the cost of equipment.
The research will be presented at the OFC Conference, the world's leading event in optical communications and network technologies, to be held in San Diego.
The developed modulator can operate in a wide range of wavelengths due to the optimized structure of the semiconductor layer and waveguide. In experiments, the new modulator demonstrated record throughput - a pure bit rate of 1.8 Tbit / s on a standard single-mode optical fiber with a length of 80 km in the C and L bands. This is the first time that an InP-based modulator operates in these bands, and the first time that a record bandwidth per wavelength for a modulator has been reported.
The following tasks include further increasing the baud rate to increase the transmission speed of information streams. At the same time, the key direction will be the development of new modulator designs that can provide extended electro-optical bandwidth while reducing power consumption and reducing the size of devices.
