Apparatus and methods for producing and/or providing recirculating optical delay(s)

摘要

Exemplary apparatus and method can be availed for providing at least one electromagnetic radiation. For example, it is possible to provide at least one first electromagnetic radiation having a frequency that changes over time with a first characteristic period. Further, with at least one hardware arrangement, it is possible to receive and modify the first electromagnetic radiation(s) into at least one second electromagnetic radiation having a frequency that changes over time with a second characteristic period. The second characteristic period can be smaller than the first characteristic period. The hardware arrangement(s) can include a resonant cavity having a round-trip propagation time for the first electromagnetic radiation(s) that can be approximately the same as the first characteristic period.

1. An apparatus for providing at least one electromagnetic radiation, comprising:
at least one source first hardware arrangement which is configured to provide at least one first electromagnetic radiation having a frequency that changes repetitively over time with a first characteristic duty cycle, wherein the first characteristic duty cycle is less than 0.5; and at least one optical system second hardware arrangement which is configured to receive and modify the at least one first electromagnetic radiation into at least one second electromagnetic radiation with a second characteristic duty cycle that is greater than the first characteristic duty cycle, wherein the second electromagnetic radiation has a frequency that changes repetitively over time with a particular period, and wherein the at least one second arrangement includes a resonant cavity having a round-trip propagation time for the at least one first electromagnetic radiation that is approximately the same as the particular period.
