A compact and low-cost continuous wave terahertz spectrometer operating at an optical wavelength of 1.5 μm is presented. The spectrometer employs high power distributed feedback (DFB) laser diodes in integrated "butterfly" packages. No further optical amplification of the beating signal is required. An integrated photodiode antenna with an output power of 5 μW at 500 GHz is used as efficient terahertz emitter. Employing low-temperature grown (LT-) InGaAs/InAlAs photoconductive receivers as coherent detectors, SNR values of the terahertz power up to 75 dB are attained at an integration time of 300 ms. Accurate characterization of the thermal tuning behavior of the DFBs and precise thermal control yield an absolute accuracy of 1 GHz and a resolution of better than 5 MHz, without any on-line monitoring of the optical frequency. Due to the high frequency resolution no delay line is needed to vary the terahertz phase.

“…Semiconductor photodetectors (PDs) with bandwidths as high as 100 GHz (Ref. 18) are used with microwave spectrum analyzers to characterize ultrafast lasers. 19 The frequency comb in a STM is also generated by optical rectification, so studies of the effects of laser noise on photodetection of mode-locked ultrafast laser pulses may be applied to the MFC in a STM.…”

“…Light that has been coupled from the four input fibers and propagates inside the single-mode waveguides is evanescently coupled to the absorbing InGaAs layer of the PDs and is detected. Details on the vertical layer stack that realizes the pin junction and allows for the evanescent coupling are presented in [26]. The size of the PD mesa is 4 × 15 μm 2 and the specific mesa design is combined with output electrical lines without a 50 Ω termination resistor.…”

We demonstrate a 2 × 100 Gb/s transmitter and a 4 × 100 Gb/s receiver as the key components for multi-100-GbE and 400-GbE optical interfaces in future intradata center networks. Compared to other approaches, the two devices can provide significant advantages in terms of number of components, simplicity, footprint, and cost, as they are capable of serial operation with nonreturn-to-zero on-off keying format directly at 100 Gb/s. The transmitter is based on the monolithic integration of a multimode interference coupler with two Mach-Zehnder modulators on an electro-optic polymer chip, and the hybrid integration of this chip with an InP laser diode and two multiplexing and driving circuits. The receiver on the other hand is based on the hybrid integration of a quad array of InP photodiodes with two demultiplexing circuits. Combining the two devices, we evaluate their transmission performance over standard single-mode fibers without dispersion compensation and achieve a BER of 10 −10 after 1000 m and a BER below 10 −8 after 1625 m at 2 × 80 Gb/s, as well as a BER below 10 −7 after 1000 m at 2 × 100 Gb/s. Future plans including the development of tunable 100 GbE interfaces for optical circuitswitched domains inside data center networks are also discussed.
