چکیده
We report the design, fabrication and characterization of a 1.55-μm dual-wavelength Distributed Bragg Reflector (DBR) laser photonic integrated circuit (PIC) chip for continuous-waves (CW) terahertz generation. The PIC consists pair parallel DBR lasers with semiconductor optical amplifiers (SOA), multimode interference (MMI) coupler combining two wavelength channels into single output waveguide. A room temperature continuous wave THz tuning range 0.06 - 0.71 was obtained through heterodyne technique.

Photonic Integrated Circuit for All-Optical Millimeter-Wave Signal Generation
Generation of millimeter-wave electronic signals and power is required for highfrequency communication links, RADAR, remote sensing and other applications. However, in the 30 to 300 GHz mm-wave regime, signal sources are bulky and inefficient. All-optical generation of mm-wave signals promises to improve efficiency to as much as 30 to 50 percent with output power as high as 100 mW. All of this ...
متن کاملHeterogeneously integrated III-V/silicon dual-mode distributed feedback laser array for terahertz generation.
We demonstrate an integrated distributed feedback (DFB) laser array as a dual-wavelength source for narrowband terahertz (THz) generation. The laser array is composed of four heterogeneously integrated III-V-on-silicon DFB lasers with different lengths enabling dual-mode lasing tolerant to process variations, bias fluctuations, and ambient temperature variations. By optical heterodyning the two...

We demonstrate how a monolithically integrated heterodyne source was used for a 33.6 GHz signal generation using an optical solution by a combination of cross-optical injection locking inside the chip and electrical injection locking at the RF signal 7th sub-harmonic.
متن کاملMonolithically-integrated distributed feedback laser compatible with CMOS processing.
An optically-pumped, integrated distributed feedback laser is demonstrated using a CMOS compatible process, where a record-low-temperature deposited gain medium enables integration with active devices such as modulators and detectors. A pump threshold of 24.9 mW and a slope efficiency of 1.3 % is demonstrated at the lasing wavelength of 1552.98 nm. The rare-earth-doped aluminum oxide, used as t...
متن کاملUltra-short distributed Bragg reflector fiber laser for sensing applications.
We present an ultra-short distributed Bragg reflector fiber laser written in Er/Yb co-doped fiber. The entire laser is only 8.4 mm in length. The lasing threshold is less than 1 mW. The optical signal-to-noise ratio of the laser output is better than 70 dB. The laser emits two orthogonal polarization modes and generates a beat signal with signal-to-noise ratio of approximately 70 dB and 3-dB li...
