Photonic distribution for cryogenic control: a design memo
How we picked SiN over SOI, why DWDM beats space-division in the fridge, and the link budget that closes from 300K to 4K with off-the-shelf components.
Tynana is a 2026 startup. Most of the artifacts below are placeholders for work in progress. We will publish technical notes and design memos as the photonic and cryo-CMOS prototypes mature — and we will be honest about what is forthcoming versus what is shipped.
Output photodetector current measured across four cascaded ring resonators tuned for an 8-channel DWDM control fabric. The spectrum confirms channel separation and individual ring tuning headroom across the 1280–1305 nm O-band window.
How we picked SiN over SOI, why DWDM beats space-division in the fridge, and the link budget that closes from 300K to 4K with off-the-shelf components.
A breakdown of static, dynamic, and IO power for an 8-channel pulse generator on GF45SPCLO, with measured leakage data from our first tapeout and the path to a 100-channel die.
A 25-minute talk on the wiring/power/latency wall — and why we believe a hybrid photonic + cryo-CMOS stack is the right architectural answer regardless of qubit modality.
A lightweight schema for describing channel maps, wavelength assignments, drive parameters, and feedback loops between a host FPGA and the Tynana control module. We will open-source the schema once it stabilizes.

A back-of-envelope comparison of conventional coax-stack control versus a Tynana-style hybrid module across three target scales — and the regime where the photonic distribution layer pays for itself.
No marketing newsletter, no fluff. You will hear from us when a tapeout returns, a paper drops, or we open a hiring round.

Tynana was incorporated in 2026. Most of the resources above are forthcoming. We have completed two foundry tapeouts (AIM Photonics SiN, GF 22nm FD-SOI) but no published peer-reviewed papers, no public benchmarks, and no shipped product. We will replace placeholders with real artifacts as they exist.
