Abstract:
1. An apparatus for preparing an erbium-doped III-V semiconductor device capable of optical amplification in the 1.54 micron wavelength band, the apparatus comprising: an erbium bubbler for providing an organic erbium vapor in hydrogen; (support paragraph 19) a metal-organic chemical vapor deposition (MOCVD) reactor; sources for at least ammonia and additional organometallic compounds, the ammonia and additional organometallic sources coupled to provide additional organometallic vapors and ammonia to the reactor; the additional organometallic compounds including gallium compounds; and a pipeline extending from the erbium bubbler to the reactor, the pipeline separate such that the organic erbium vapor does not mix with the ammonia and additional organometallic compounds until the erbium vapor, ammonia, and additional organometallic compounds are inside the reactor.
