摘要： A laser for generating an output wavelength of approximately 193.4 nm includes a fundamental laser, an optical parametric generator, a fourth harmonic generator, and a frequency mixing module. The optical parametric generator, which is coupled to the fundamental laser, can generate a down-converted signal. The fourth harmonic generator, which may be coupled to the optical parametric generator or the fundamental laser, can generate a fourth harmonic. The frequency mixing module, which is coupled to the optical parametric generator and the fourth harmonic generator, can generate a laser output at a frequency equal to a sum of the fourth harmonic and twice a frequency of the down-converted signal.

摘要： It is an objective of the present invention to provide a phase sensitive amplifier that can be used for an optical communication and that can provide low-noise amplification. The phase sensitive amplifier according to the present invention is a phase sensitive amplifier that uses the optical mixing using a nonlinear optical effect to amplify the signal light. The phase sensitive amplifier according to the present invention includes: the first second-order nonlinear optical element (602-1); and the second second-order nonlinear optical element (602-2). The first second-order nonlinear optical element (602-1) causes the fundamental wave light (621) to generate second harmonic light (622) used as pump light. A filter (606-1) is provided that spectrally separates only the second harmonic light from the fundamental wave light and the second harmonic light. The second second-order nonlinear optical element (602-2) includes a multiplexer (606-2) to multiplex the signal light with the second harmonic light. The multiplexed signal light and second harmonic light are used subjected to parametric amplification. A filter (606-3) is provided that spectrally separates only the amplified signal light from the second harmonic light and the amplified signal light.

摘要： A wavelength conversion device including a nonlinear medium (20) having quantum dots (24) uses a tunable laser as an excitation light source of optical four wave mixing, and performs wavelength conversion for a wide bandwidth signal light with optical four wave mixing. The nonlinear medium (20) is disposed on an n type GaAs [100] orientation substrate (21) and includes an n type AlGaAs clad layer (22) formed on the substrate (21) and a lower part SCH layer (23) including non-doped GaAs formed on the clad layer (22). An island-like area of non-doped InAs or InGaAs, which is formed by S-K mode growth is formed on the SCH layer (23) as quantum dots (24) and a non-doped GaAs barrier layer (25) is formed on the SCH layer (23) in a manner covering the quantum dots (24). An upper part SCH layer (27) including non-doped GaAs is formed on the acive layer (26) and a p type AlGaAs clad layer (28) is formed on the upper part SCH layer (27). An upper part electrode (29) is formed on the clad layer (28) and a lower part electrode (30) is formed on a bottom surface of the substrate (21).
