4 Gbps PAM-4 and DMT Free Space Transmission using a 4.65-pm Quantum Cascaded Laser at Room Temperature

• We experimentally demonstrate 4Gbps PAM-4 and DMT transmissions using a quantum cascaded laser (QCL) emitting at mid-wavelength infrared of 4.65μm and a commercial infrared photovoltaic detector. The QCL is directly modulated and operated at room temperature with Peltier Cooling.
