Semiconductor Arrayed Waveguide Grating Channel Spacing Calculator
Actual ordered AWGchannel-center wavelength differences. Not free spectral range, frequency-equal spacing or a prescribed optical design.
Description
An arrayed waveguide grating separates wavelength channels through interference in an array of optical paths.
An arrayed waveguide grating separates wavelength channels through interference in an array of optical paths.1
Adjacent channel spacings are measured differences rather than a device layout calculation.
When to use Semiconductor Arrayed Waveguide Grating Channel Spacing Calculator
Use this tool to calculate or review the supplied observations under the stated rules. Establish the device or material, operating point, units and independently applicable measurement or model calibration.
How to use Semiconductor Arrayed Waveguide Grating Channel Spacing Calculator and understand its results
- Establish the device or material, operating point, units and independently applicable measurement or model calibration.
- Enter actualChannelCenterWavelengthsNm, using the field meanings and rules below, then run the tool.
- Read result.observedAdjacentChannelSpacingsNm. Use the units and sign conventions below.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| actualChannelCenterWavelengthsNm | Actual channel center wavelengths nm | list of number | Required |
Require at least two strictly increasing positive channel wavelengths in nanometers. Return each next-minus-current difference without converting to frequency or requiring equal spacing.
spacingNm_i=wavelength_(i+1)−wavelength_i Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Structured result; its nested fields below contain the actual calculation or selected reference | object |
| result.observedAdjacentChannelSpacingsNm | Observed Adjacent Channel Spacings Nm | list |

}Limitations and assumptions
Device structure, material state, operating conditions and calibration determine applicability. The result does not infer missing physical parameters or verify a mechanism.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Lists and matrices must be dense, without missing cells. Numeric lists allow at most 10000 entries; ordinary string lists allow at most 128 strings of 128 UTF-16 units each; numeric matrices allow at most 128 rows and 128 columns, subject to narrower requirements above. Extremely large composite outputs are rejected.

For a complementary comparison, use Semiconductor Band Filling Blueshift Calculator: Band filling can shift observed optical transitions as occupied carrier states change.
