Table 1 Comparison of on-chip device with alternative techniques
From: Universal photonic processor for spatial mode decomposition
Technique | Number of modes | Polarization decomposition | Scalability | Compact and on-chip integration | Data acquisition time |
|---|---|---|---|---|---|
Shack–Hartmann35 | High (Microlens array dependent) | No | Yes | No | Single shot |
SLM-based7 | 210 modes | No | Yes | No | Single shot |
Off-axis Holography36 | High (sensor size dependent) | No | Yes | No | Single shot |
On-chip device (Current work) | 9 modes | Yes | Yes | Yes | Few minutes |
