    Abstract: Regarding an optical pulse reshaping device of CPF type, there are subjects to reduce the number of stages by enhancing a compression efficiency as extremely higher for one stage of the CPF with maintaining a quality of an output pulse as high, and to be able to improve a degree of multiplexing by obtaining an output pulse having a Gaussian function for both of a time waveform therefor and a frequency waveform therefor. By using a normal dispersion HNLF in place of a zero dispersion HNLF, which configures the conventional CPF, it becomes able to overcome the above mentioned subjects. Moreover, it becomes able to reduce the number of fusion splice for a fiber, and to reduce a propagation loss of the CPF, by enhancing the compression efficiency as higher.

    Abstract: An optical device is configured to perform both switching and attenuation of an optical beam in response to a single control signal. The optical device includes a liquid-crystal-based beam-polarizing element having polarization-conditioning regions that are controlled using a common electrode. The first polarization-conditioning region conditions the polarization of the input beam in order to separate the input beam into a primary component and a residual component. The second and third polarization-conditioning regions change the polarization of the primary component and the residual component, respectively. The primary component is directed to an output port after it has been attenuated based on its polarization state. The residual component, after passing through the third polarization-conditioning region, has its intensity further reduced based on its polarization state.
