    摘要: An object of the invention is to provide an optical integrated device which enables to supply a wide range of variable wavelength and to reduce the coupling loss. The optical integrated circuit chip (10) includes a semiconductor optical amplifier section (20), a phase control section (18), a partially reflecting mirror (16) having optical power splitter function and a Mach-Zehnder optical modulator (22), wherein all elements are formed on a same substrate monolithically. On each facet of the optical integrated circuit chip (10), an Anti-Reflection coating (12, 14) is formed respectively. A lens (30), an optical filter (32) and an external resonator mirror (28) are located outside of the optical integrated circuit chip (10), wherein an external cavity laser is formed with a semiconductor optical amplifier (SOA) section (20) operating as gain section, a partially reflecting mirror (16) operating as first reflecting mirror and an external resonator mirror (28) operating as a second mirror.
