Figure 2

Schematic of all fibre-based JSI measurement setups showing (a) the pulsed fibre laser, polarisation controller (PC), optical isolator (ISO), variable attenuator (ATT), tunable band-pass filter (TBPF), power meter (PM), external cavity diode laser (ECDL), erbium-doped fibre amplifier (EDFA), pulse generator (PG), intensity modulator (IM), arrayed waveguide grating (AWG), (b) buried silicon nanowire (SiNW) and the simulated energy density of the fundamental TE mode, (c) liquid-crystal-on-silicon dynamically tunable filter (LCoSWS, Finisar WaveShaper), superconducting single photon detector (SSPD, Single Quantum—polarisation sensitive), time interval analyser (TIA) and optical spectrum analyser (OSA).
