Apparatus and method for utilization of a high-speed optical wavelength tuning source |
摘要 |
Exemplary embodiments of apparatus, source arrangement and method for, e.g., providing high-speed wavelength tuning can be provided. According to one exemplary embodiment, at least one arrangement can be provided which is configured to emit an electromagnetic radiation that (i) has a spectrum whose mean frequency changes at an absolute rate that is greater than about 6000 (or 2000) terahertz per millisecond, (ii) whose mean frequency changes over a range that is greater than about 10 terahertz, and/or (iii) has an instantaneous line width that is less than about 15 gigahertz. According to another exemplary embodiment, at least one arrangement can be provided configured to, periodically and as a function of time, select at least one first electro-magnetic radiation based on a mean frequency of the at least one first electro-magnetic radiation, with the periodic selection being performed at a first characteristic period. The mean frequency can vary linearly over time, wherein the apparatus can emit at least one second electromagnetic radiation that has a spectrum whose mean frequency changes periodically as a function of time with a second characteristic period. Further, the first characteristic period can be greater than the second characteristic period. |

1. An apparatus comprising:
at least one wavelength swept laser arrangement configured to emit an electromagnetic radiation that has a spectrum whose mean frequency changes (i) at an absolute rate that is greater than about 6000 terahertz per millisecond, and (ii) over a range that is greater than about 10 terahertz, wherein the spectrum has an instantaneous line width that is smaller than 100 gigahertz. |
