Abstract

A frequency doubled erbium doped modelocked fiber frequency comb is used to implement a THz photomixing synthesizer. The useful THz linewidth is in order of 150 kHz and has been assessed along with the frequency accuracy by spectroscopic measurements demonstrating a relative accuracy of 10−8 at frequencies around 1 THz. The THz synthesizer is used to implement a THz spectrometer to study the rotational absorption spectrum of carbonyl sulfide (OCS). Measurement of the principal transitions between 813 GHz and 1283 GHz allowed the properties of the THz spectrometer to be compared with competing techniques, and demonstrates the potential of the THz photomixing synthesizer as an alternative means to explore the THz domain.

Experimental setup of the synthesised THz source. A first beam splitter (BS1) is used to overlap the two laser beams from the two External Cavity Diode Laser (ECDL) and seed them to Tapered Amplifier (TA). At the output, optical beat note is divided by a second beam splitter (BS2). A first part is used to produce the THz radiation collected at the backside of the photomixer by a silicon lens. Two Off axis Parabolic Mirrors (OPM) are used to collimate and focus the THz beam through an absorption cell to a cryogenic bolometer. The frequency comb (FC) is overlap with optical beat note by means of a third beam splitter (BS3). Two grating (G) disperse the FC and two lasers to ensure an heterodyne measurement between each ECDL and FC detected by two different photodiodes (PD1- PD2). The heterodyne signals are feed to two Phase Lock Loop (PLL) to synthesized the difference frequency between two ECDL to a synthesizer. A 10 MHz crystal oscillator is used as reference signal for synthesizers, counters and spectrum analyzers required. Solids lines show optical signal, and dashed lines indicate electronic signal.
