- Abstract
- Disclosed is a frequency swept source apparatus including a mode locking laser that outputs an input optical signal having first to n-th frequency components, a transmission delay controller that generates first to m-th sub-optical signals, each of which includes at least one component of the first to n-th frequency components, and outputs a delay optical signal obtained by sequentially delaying the first to m-th sub-optical signals. The transmission delay controller includes a demultiplexer that outputs the first to m-th sub-optical signals to first to m-th channels based on the input optical signal, respectively, a path delay unit that adjusts lengths of optical paths of the first to m-th channels so as to be different from one another, a refractive index controller that adjusts a refractive index of each of the first to m-th channels, and a multiplexer that combines the first to m-th sub-optical signals.
