01 / About
Light is becoming a fundamental layer of modern technology.
I’m David Domenech, an engineer working at the intersection of photonics, semiconductors and telecommunications.
λ39 is my independent space for ideas, technical exploration and projects — from integrated photonics and optical communications to the broader technologies shaping the future.
Semiconductors
Devices, materials, fabrication and the technologies behind modern hardware.
Telecommunications
Optical networks, coherent communications and the infrastructure connecting our world.
Technology
Engineering, deep tech and observations on where technology is heading next.
02 / Writing
Notes from the field.
