Brain-Machine Interfaces (BMI) offer the potential to modulate dysfunctional neurological networks by electrically stimulating the cerebral cortex via chronically-implanted microelectrodes. Wireless transmitters worn by BMI recipients must operate wi

The combination of polarization-multiplexing (pol-mux) high-order quadrature-amplitude-modulation (QAM) format and non-data-aided (NDA) channel equalization largely enhances the spectral efficiency of the coherent optical systems. In this paper, we p

We demonstrate an RF photonic fractional Hilbert transformer based on an integrated Kerr micro-comb source featuring a record low free spectral range of 48.9 GHz, yielding 75 microcomb lines across the C-band. By programming and shaping the comb line

Kramers-Kronig (KK) receivers have been shown to be able to cancel the signal-signal beat interference that occurs upon direct-photodetection in optical single-sideband systems, where the transmitted optical field is proportional to the modulation si

Theoretically, for continuous signals, Kramers–Kronig (KK) receivers should be able to precisely reconstruct a band-limited signal's phase from its envelope if the minimum phase (MP) condition is satisfied. However, simulations have shown that even

Theoretically, Kramer–Kronig (KK) receivers are able to fully cancel signal-signal beat interference (SSBI), which results from a field-modulated single-sideband (with carrier) transmitter being used with a direct-detection receiver. However, even

We demonstrate an all-analogue converter from optical intensity modulated direct-detection double-side-band signals to field-modulated optical coherent signals, which is based on the Weaver method of generating SSB radio signals. Our format converter

Advanced image processing will be crucial for emerging technologies such as autonomous driving, where the requirement to quickly recognize and classify objects under rapidly changing, poor visibility environments in real time will be needed. Photonic
