英文摘要 | The disclosed integrated modulator/laser (I-MOD/DFB) combination comprises an active region that extends the full length of the combination without variation of layer thickness and/or composition. Because of this constancy of the active region parameters the relevant bandgap energy is the same in the laser portion of the combination as in the modulator portion thereof. The combination typically comprises a distributed feedback structure (e.g., a "grating"). In preferred embodiments the feedback structure is selected such that lambda e> lambda o (typically lambda e- lambda o in the range 20-70 nm), where lambda e is the laser output wavelength, and lambda o is the wavelength of the gain peak of the laser medium. The active region can be a bulk active region but preferably is a quantum well active region. Optionally an I-MOD/DFB combination according to the invention can comprise an absorbing region, e.g., an ion implanted region between the laser section and the modulator section. Combinations according to the invention typically are easier to manufacture than prior art combinations, and are advantageously used in e.g., optical fiber communication systems. |
