Spectral Efficiency and Receiver Sensitivity in Direct Detection Optical-OFDM

For high linearity, the MZM is biased at its quadrature point (i.e. Vbias/Vπ=0.5), where Vπ is the switching voltage at which the voltage-induced phase difference reaches 1800. For fixed bias, carrier power is fixed, too. N ...

Superheterodyne receiver
In electronics, a superheterodyne receiver (often shortened to superhet) uses frequency mixing to convert a received signal to a fixed intermediate frequency (IF) which can be more conveniently processed than the original radio carrier frequency. It was invented by US engineer Edwin Armstrong in 1918 during World War I. Virtually all modern radio receivers use the superheterodyne principle. At the cost of an extra frequency converter stage, the superheterodyne receiver provides superior selectivity and sensitivity compared with simpler designs.
