  • 10 Gbit per second! Unipolar quantum photoelectrons transmit free space data at 9 µ m wavelength

    Jiangsu laser alliance Guide: The bit rate exceeds 10 Gbit S − 1 free space optical data transmission at 9 &Micro by using a unipolar quantum photoelectric system at room temperature; The system is composed of quantum cascade laser, modulator and quantum cascade detector. This demonstration of high bit rate data transmission sets unipolar quantum devices as the best platform for the development of mid infrared VHF optoelectronic systems for a variety of applications such as digital communication and high-resolution spectroscopy 1 Introduction Unipolar Quantum Optoelectronics (uqos) is a group…
