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： The present invention provides for a transceiver comprising a transmitter portion and a receiver portion. The transmitter portion includes a laser, the laser providing an optical signal having one of a plurality of wavelengths. The optical signal from the laser is modulated to create a first wavelength-division multiplexed signal at an output of the transceiver. The optical signal from the laser is also used by a demultiplexer to demultiplexer a second wavelength-division multiplexed signal at an input of the transceiver. The use of the optical signal from the laser in both modulation and demodulation of wavelength-division multiplexed signals results in a transceiver having fewer discrete components resulting in a compact design and reduced costs.

摘要： A method of calibrating a monolithic transmitter photonic integrated circuit (TxPIC) chip is disclosed where the chip contains integrated arrays of laser sources and electro-optic modulators forming a plurality of different wavelength signal channels where each laser source on the chip is sequentially selected and tested for the output power and operational wavelength. Calibration data is initially determined by checking an amount of output power of each laser output and any offset of each laser operational wavelength from a desired predetermined value. Then, adjustment of the operational wavelength of each laser source is accomplished to substantially match the desired predetermined value. The laser source output power and operational wavelength may then be rechecked to determine if there is any remaining offset of each laser operational wavelength from the desired predetermined value. If so, the laser source output power can be readjusted to a desired amount and its operational wavelength can be readjusted to the desired predetermined wavelength value. The final calibration data it then stored for future reference as a benchmark in later adjustment of laser source output power and operational wavelength for each laser source on the tested chip when the chip has been installed in the field.
摘要翻译：公开了一种校准单片发射器光子集成电路（TxPIC）芯片的方法，其中芯片包含激光源的集成阵列和形成多个不同波长信号通道的电光调制器，其中芯片上的每个激光源被依次选择和测试用于输出功率和工作波长。最初通过检查每个激光输出的输出功率的量和每个激光操作波长与期望的预定值的任何偏移来确定校准数据。然后，实现每个激光源的工作波长的调整，以使其基本匹配所需的预定值。然后可以重新检查激光源输出功率和操作波长，以确定每个激光操作波长是否存在与期望的预定值的任何剩余偏移。如果是这样，则可以将激光源输出功率重新调整到期望的量，并将其工作波长重新调整到期望的预定波长值。最后的校准数据，然后存储在将来参考作为基准，以后调整激光源输出功率和每个激光源在测试芯片上的操作波长，当芯片已经安装在现场。
