Partners

Your part, in the design loop

Today a component reaches a designer as a PDF and a part number: specs on page nine, no model to simulate, no way to check it against the rest of the chip. So it gets designed around. A listing here is the opposite of that — the part becomes data a designer can search, simulate and specify in the place they are already designing.

Component & IP vendors

What a listing actually contains

Not a logo on a partner wall. A record a designer can work with: filed by function, carrying the geometry and the ports, and tagged with the band it operates in.

Geometry, not a picture
Each part opens with its layout sketch, its size in microns, and its cross-sections — including the width and the minimum bend radius a designer has to respect. The cell carries the ports that connect it, so it lands in a layout as something that routes.
Simulate before you specify
A part ships with its S-parameter files, tagged by band — O-band at 1310 nm or C-band at 1550 nm — so a designer can drop it into a circuit and see what it does to the link before it is chosen, not after.
Filed where designers look
By function and by class — active, passive, I/O, electrical, test, assembly or laser — alongside the process design kit's own cells. Your part is found by the people choosing what to put on the die.

Laser sources

The spec sheet a designer can use

Laser sources get their own record, because the questions a designer asks about a laser are not the questions they ask about a waveguide.

What a laser listing carries
FieldWhy a designer needs it
Type and wavelength bandsWhich device it is, and where it works — O-band, C-band, or both.
Output power and linewidthThe two figures that decide whether a link closes.
Modulation bandwidthWhether it can be modulated directly, or needs an external modulator.
Integration methodSubmount, bonded, micro-transfer-printed, or grown — because that decides the process.
Best for, and suppliersWhere the part wins, and who can supply it.
Pros and consThe honest version, including where it is the wrong choice.
Fabricated and characterizedWhether the part exists in silicon and has been measured.

Including the cons. A listing that only lists advantages is a datasheet, and designers have learned not to trust those. Where a part is the wrong choice, the listing says so.

Measured, not nominal

The curve, not the specification

A part is only as good as the measurement behind it. So the catalogue shows measured spectra with real loss figures, and the platform keeps a measurement library to calibrate against.

Measured spectra
Grating-coupler spectra are shown as measured — O-band against C-band, from the same strip cell — with the figures a designer actually uses: the best insertion loss in the window, the wavelength it occurs at, and the 1-dB bandwidth. Insertion loss is fibre-to-chip coupling loss, so lower is better, and the plot says so.
A measurement library to calibrate against
Measurements are kept per component and per platform, and they feed the surrogate models that make exploration cheap. When a fabricated part disagrees with the model, that is data, and it gets used.

Test & assembly vendors

Listed by stage, throughput and cost

If you sell test or assembly rather than parts, the same principle applies: a test team should be able to plan capacity around you, not ring you to ask.

The four production test stages
StageWhat happens there
Stage 1: Wafer SortKnown-good-die identification on the photonic and electronic wafer.
Stage 2: Integrated E-OElectro-optic test at the wafer level, where the two domains meet.
Stage 3: Optical EngineOptical engine test, once the dies are assembled into an engine.
Stage 4: Module TestFinal module test, at the point the product ships.

A listing carries your key capability, your throughput in dies per hour, and your cost per hour. Those three figures are what let a test team model the whole chain — and see which stage is the bottleneck before the parts are built rather than after.

Already in the directory

We may already hold a record for your company

Our directory holds thousands of organisations, built from public sources — not from anything you sent us. Find yours, see what we hold, and tell us what is wrong or missing. A person reviews every claim before anything is published.

Calibrated honesty

What we need from a partner, and what we will not do

Measured data, not nominal specs
A part with a measured curve is worth listing. A part with a nominal figure and no measurement can still be listed — but it will say so, because a designer who specifies it on a nominal number and gets a surprise at test blames the catalogue, correctly.
We do not publish your data without agreement
Your measurements, your geometry and your pricing are yours. Nothing goes into a public listing without your written agreement, and nothing goes in at all under an NDA you have not cleared.
