    摘要: The present disclosure relates to the design of fiber frequency comb lasers with low carrier phase noise. Examples of these low carrier phase noise oscillators can be constructed from both soliton and dispersion compensated fiber lasers via the use of intra-cavity amplitude modulators such as graphene modulators. In low carrier phase noise dispersion compensated fiber frequency comb lasers, graphene and/or bulk modulators can further be used, for example, for phase locking of one comb line to an external continuous wave (cw) reference laser via high bandwidth control of the repetition rate of the comb laser via the graphene modulator. As a result a low phase noise radio frequency (RF) signal can be generated. In some implementations, a frequency comb exhibiting phase noise suppression of at least about 10 dB over a frequency range up to about 100 kHz is provided.

    摘要: A surface emitting laser is provided which requires a smaller number of components, and which can reduce the cost. A surface emitting laser includes a cavity constituted by a first reflecting mirror (101) and a second reflecting mirror (102), and having a resonant wavelength that is changed by changing a cavity length with movement (106) of the first reflecting mirror (101) in a direction facing the second reflecting mirror. The surface emitting laser further includes an active layer (105) arranged in the cavity and emitting light, a third reflecting mirror (103) arranged on the opposite side of the active layer (105) with respect to the second reflecting mirror (102), and a light receiving element (104) arranged to receive light passing through the third reflecting mirror. The wavelength sweeping VCSEL may comprise a first DBR (101) on a deformable support (303) which is in turn supported by a further support (302). The active layer (105) may be a MQW on a second DBR (102) on a substrate (107) having a hole for back-side emission for the radiation to be detected by a photodiode (104). The detected radiation is frequency filtered by a Fabry-Perot resulting from the second DBR (102) and a low reflectivity third reflector (103) realized by the interface between the uncoated lower surface of a quartz substrate (103) and air. Anti-reflective coatings (301,306) on the other outer surfaces prevent undesired further Fabry-Perot resonators. Choosing the FSR of this Fabry-Perot correspondingly, a clock signal for OCT applications can be derived from the Fabry-Perot filtered and detected back-side emission of the VCSEL.
