Patent ID: 7106774

Claim:
An amplified laser comprising: a substrate, a semiconductor optical amplifier (SOA), coupled to the substrate and including an amplifier anode electrode and an amplifier cathode electrode, a semiconductor laser, coupled to the substrate and including a semiconductor laser anode electrode and a semiconductor laser cathode electrode, and an electro-absorption modulated laser (EML) package that encloses the semiconductor laser and the SOA, the EML package including: a first electrical contact electrically coupled to at least one of the anode electrode of the SOA or the anode electrode of the semiconductor laser; a second electrical contact electrically coupled to at least one of the cathode electrode of the SOA or the cathode electrode of the semiconductor laser; and an optical output port configured to provide an output amplified optical signal; wherein; the semiconductor laser and the SOA are configured on the substrate so that the laser is optically coupled to the SOA; and at least one of the semiconductor laser anode electrode or semiconductor laser cathode electrode is electrically coupled to at least one of the amplifier anode electrode or amplifier cathode electrode such that the semiconductor laser and the SOA are electrically connected in series.
