Chips & lab

Automatic tuning setup
Automatic tuning setup The full bench: heater-control boards, the photonic chip on its carrier, and fiber alignment stages. February 2023.
Heater-control board
Heater-control board Multichannel DAC board that drives the on-chip heaters, with the Arduino that runs the tuning loop.
Fiber alignment on the optical bench
Fiber alignment on the optical bench Precision stages position fibers over the grating couplers of the photonic chip.
Photonic chip under test
Photonic chip under test Silicon photonic chip on its RF test board during probing. July 2022.
Landing the probes
Landing the probes RF probe and fiber array positioned over the chip under the microscope light.
Wire-bonded photonic chip
Wire-bonded photonic chip The PIC bonded to the board, with RF connectors on either side.
Chip under the microscope

Microscope camera view
Microscope camera view Live camera view of the chip used to align probes during measurement.
Wide wavelength sweep
Wide wavelength sweep Measured insertion loss of a ring-resonator filter across a wide sweep, showing the comb of resonances.
Resonances up close
Resonances up close A narrower sweep of the same measurement, showing individual resonance dips.
Optical spectrum check
Optical spectrum check Checking the optical spectrum on an Anritsu MS9710B during link testing.
