Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In the European project MORPHIC we develop a platform for programmable silicon photonic circuits enabled by waveguide-integrated micro-electro-mechanical systems (MEMS). MEMS can add compact, and low-power phase shifters and couplers to an established silicon photonics platform with high-speed modulators and detectors. This MEMS technology is used for a new class of programmable photonic circuits, that can be reconfigured using electronics and software, consisting of large interconnected meshes of phase shifters and couplers. MORPHIC is also developing the packaging and driver electronics interfacing schemes for such large circuits, creating a supply chain for rapid prototyping new photonic chip concepts. These will be demonstrated in different applications, such as switching, beamforming and microwave photonics.

Programmable silicon photonic circuits powered by MEMS

Konferensbidrag (refereegranskat)abstract
- We present our work to extend silicon photonics with MEMS actuators to enable low-power, large scale programmable photonic circuits. For this, we start from the existing iSiPP50G silicon photonics platform of IMEC, where we add free-standing movable waveguides using a few post-processing steps. This allows us to implement phase shifters and tunable couplers using electrostatically actuated MEMS, while at the same time maintaining all the original functionality of the silicon photonics platform. The MEMS devices are protected using a wafer-level sealing approach and interfaced with custom multi-channel driver and readout electronics.

Scaling programmable silicon photonics circuits

Ingår i: Silicon Photonics XVIII. - : SPIE-Intl Soc Optical Eng.

Konferensbidrag (refereegranskat)abstract
- We give an overview the progress of our work in silicon photonic programmable circuits, covering the techn stack from the photonic chip over the driver electronics, packaging technologies all the way to the sof layers. On the photonic side, we show our recent results in large-scale silicon photonic circuits with diff tuning technologies, including heaters, MEMS and liquid crystals, and their respective electronic driving sch We look into the scaling potential of these different technologies as the number of tunable elements in a ci increases. Finally, we elaborate on the software routines for routing and filter synthesis to enable the pho programmer.

A Bistable Silicon Photonic Mems Phase Switch For Nonvolatile Photonic Circuits
- 2022
-
Konferensbidrag (refereegranskat)abstract
- Silicon photonic circuits are rapidly growing in complexity and spreading to new applications. However, programmable circuits consume much power and require active electrical interfaces. For the first time, we demonstrate a nonvolatile photonic MEMS π-phase switch using dual comb-drive actuation and adhesion forces, implemented in a silicon photonics foundry. Both nonvolatile states are low-loss, display low dispersion, could be cycled through over 100 times, and have retention times over 12 hours. We believe that the demonstrated nonvolatility combined with excellent optical performance can enable a new generation of programmable photonic chips that do not consume any electrical power once (re)configured.

A vacuum-sealed silicon photonic MEMS tunable ring resonator with independent control over coupling and phase
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Ring resonators are a vital element for designing filters, optical delay lines, or sensors in silicon photonics. However, reconfigurable ring resonators with low-power consumption and good optical performance are not available in foundries today. We demonstrate an add-drop ring resonator with the independent tuning of coupling and round-trip phase using low-power microelectromechanical (MEMS) actuation. The MEMS rings are individually vacuum-sealed on wafer scale, enabling reliable long-term operation with low damping. On resonance, we demonstrate a modulation increase of up to 15 dB, with a voltage bias of 4V and a peak drive amplitude as low as 20mV.

- Ring resonators are a vital element for filters, optical delay lines, or sensors in silicon photonics. However, reconfigurable ring resonators with low-power consumption are not available in foundries today. We demonstrate an add-drop ring resonator with the independent tuning of round-trip phase and coupling using low-power microelectromechanical (MEMS) actuation. At a wavelength of 1540 nm and for a maximum voltage of 40 V, the phase shifters provide a resonance wavelength tuning of 0.15 nm, while the tunable couplers can tune the optical resonance extinction ratio at the through port from 0 to 30 dB. The optical resonance displays a passive quality factor of 29 000, which can be increased to almost 50 000 with actuation. The MEMS rings are individually vacuum-sealed on wafer scale, enabling reliable and long-term protection from the environment. We cycled the mechanical actuators for more than 4 x 109 cycles at 100 kHz, and did not observe degradation in their response curves. On mechanical resonance, we demonstrate a modulation increase of up to 15 dB, with a voltage bias of 4 V and a peak drive amplitude as low as 20 mV.
