Hmmm, ok - probably wouldn't fit anywhere. It's not an announcement or rumour of an upcoming diode. It's not commercially available (but just expensive or unattainable by us). It's also not common (obviously).
And I think that's cool - I think that's how one-offs should be handled. Otherwise the list doesn't serve much of a purpose, since I'm sure there are (as has been said before) tons of one-offs created at different wavelengths.
