Single soliton microcombs enable the chip-scaled comb source with an extremely high repetition rate suitable for many applications. However, it is challenging to deterministically generate a single…
We report a LiDAR transmitter incorporating both a hybrid-integrated tunable external cavity laser and a high-resolution 2-D optical phased array beam-steerer. Widely tunable single-mode lasing ove…
The ‘Mach-Zehnder modulator (MZM)–wavelength division demultiplexer (WDM)–photodetector (PD)’ structure in photonic analog-to-digital converters (PADCs) may result in residual even harmonic…
We demonstrate a 1×8 binary tree optical beamforming network (OBFN) chip for a microwave photonic phased array antenna. The OBFN is formed by cascading multiple microring resonators (MRRs) working…
We report a wavelength widely-tunable hybrid integrated external cavity laser (ECL) with synchronous tuning to achieve a large frequency chirp bandwidth and high chirp linearity. Si 3 N 4 Vernier m…
Vector network analyzers (VNAs) are established as one of the indispensable tools for measuring and analyzing the characteristics of objects under test in various fields, ranging from medicine and …
High-stability optical frequency comparison over fiber link enables the establishment of ultrastable optical clock networks, having the potential to promote a series of applications, including metr…
The effects of the nonlinearity caused by the structure of ‘Mach-Zehnder modulator (MZM) - wavelength division demultiplexer (WDM)’ in Time-Wavelength Interleaved Photonic Analog-to-Digital Con…
In this paper, we experimentally demonstrate an ultra-long haul and multi-access fiber-optic time synchronization system over the equivalent 13 134 km fiber link based on the bidirectional time div…
We report a silicon-based integrated optical sampling chip. High-repetition-rate optical sampling pulses are generated by interleaving low-repetition-rate input optical pulses with the assistance o…
