摘要： An optical-to-electrical-to-optical converter comprises a monolithic receiver photonic integrated circuit (RxPIC) InP-based chip comprising an optical waveguide formed in the chip from a chip input to receive a first multiplexed channel signal from an optical link and provide them to an arrayed waveguide grating (AWG) which demultiplexes the multiplexed channel signals and provides a plurality of electrical channel signals to an electronic regenerator. The regenerator regenerates the electrical channel signals to an original signal waveform and provides the reformed electrical signals to a monolithic transmitter photonic integrated circuit (TxPIC) InP-based chip having an array of modulated sources formed in the chip that are coupled as inputs to an arrayed waveguide grating (AWG). The TxPIC modulates the reformed electrical signals to form a plurality of optical channel sign which are combined to form a second first multiplexed channel signal for transmission on an optical link.

摘要： A semiconductor monolithic transmitter photonic integrated circuit (TxPIC) comprises two different situations, either at least one signal channel in the PIC having a modulated source with the channel also extended to include at least one additional element or a plurality of modulated sources comprising N signal channels in the PIC of different transmission wavelengths, where N is equal to or greater than two (2), which may also approximate emission wavelengths along a standardized wavelength grid. In these two different situations, a common active region for such modulated sources and additional channel elements is identified as an extended identical active layer (EIAL), as it extends from a single modulated source to such additional channel elements in the same channel and/or extends to additional modulated sources in separate channels where the number of such channels is N equal to two or greater. The emission wavelength of laser sources in the modulated sources have different positively detuned offsets of the laser emission wavelength relative to the laser active region wavelength, i.e., (λL,i−λPL,L,j>0), and their emission wavelengths form a wavelength grid which may substantially conform to a standardized wavelength grid, such as the ITU grid. These laser sources in the modulated sources with an EIAL are preferentially detuned in the range, for example, of about 20 nm to about 70 nm, preferentially from about 25 nm to about 50 nm, from the active region wavelength of the modulated sources.

摘要： A monolithic photonic integrated circuit (PIC) chip comprises an array of modulated sources providing a plurality of channel signals of different wavelengths and an optical combiner coupled to receive the channel signals and produce a combined output of the channel signals. The arrays of modulated sources are formed as ridge waveguides to enhance the output power from the respective modulated sources so that the average output power from the sources is approximately 2 to 4 times higher than in the case of comparable arrays of modulated sources formed as buried waveguides.

摘要： A monolithic photonic integrated circuit (PIC) chip where the active waveguide cores of the modulated sources of the PIC are multiple quantum wells (MQWs) and the passive waveguide cores of an optical combiner are a bulk layer or material. The cores of the waveguide cores may be a quaternary such as InGaAsP or InAlGaAs.
