“…Several solutions have been proposed to provide a regularly spaced frequency comb, such as a Fabry-Perot interferometer or a fibre ring resonator [3]. Unfortunately the frequency accuracy and stability of these devices are limited by the optical length of the resonators.…”

“…We have overcome these limitations by combining injection locking and phase locking in an optical injection phase lock loop (OIPLL) [11]. For these experiments the comb source was an amplified fibre loop with embedded phase modulator as in [3]. Its spectrum was delivered to (slave) lasers in OIPLL blocks (combined OIL and OPLL), which were locked to selected lines.…”

“…Then by taking the result of simulation for the coupling into the waveguide we can estimate the coupled power into the photodetector to be 5 dBm. The second measurement system, used a signal from an heterodyne system based on an optical frequency comb generator [3], from which two lines were filtered out by tuneable narrowband filters. The two lines were then combined and amplified to generate a signal at a frequency determined by their separation.…”

-In this paper we present a review of our work on photonic synthesis of high spectral purity THz signals. This work includes novel developments on optical frequency comb generation (integrated, 2THz span, 25 GHz spacing), frequency locking of semiconductor lasers (1kHz channel stability, 10 ns switching time) and high speed photodetectors integrated with antennas (3dB bandwidth >108 GHz, 0.2 A/W responsivity , 148 µW output power at 457 GHz).

We describe the generation of terahertz optical frequency comb using the spontaneous emissions from a semiconductor optical amplifier as the signal source. The source drives an all-fiber LYOT-Sagnac birefringent fiber. This transforms the broad band source into a discrete set of evenly spaced frequencies. The output of the Sagnac loop mirror is then coupled to fiber pigtailed Faraday Mirror reflecting the optical frequency comb back into the optical amplifier for further amplification. The method resulted in generating optical frequency comb ranging from 183THz to 213 THz with frequency spacing of 560 GHz.

“…Atomic or molecular resonances are commonly used to provide absolute frequency references, however they are limited to a few particular frequencies [1]. To overcome such limitation several other solutions have been proposed to provide a regular spaced frequency comb, such as a Fabry-Perot interferometer or a fibre ring resonator [2]. Unfortunately the frequency accuracy and stability of these devices are limited by the optical length of the resonators.…”

-We report a monolithic optical frequency comb generator using quaternary/quaternary multiple quantum well InP/InGaAsP material as phase modulator and gain medium in a Frequency Modulated (FM) laser design. The modulation was generated by quantum confined Stark effect to achieve a comb-line spacing of 24.4 GHz. The laser was fabricated using a single epitaxial growth step and quantum well intermixing to realize low loss phase and modulation sections. The resulting comb generator produces lines with a spacing exactly given by the modulation frequency, differential phase noise between adjacent lines of -82 dBc/Hz at 1 kHz offset and a comb spectrum width of up to 2 THz.
