Provided is an exhaust gas purifying filter which shortens the combustion time of the particulate matter that is deposited on the partition walls, during the regeneration of a ceramic honeycomb structure, while maintaining the efficiency of capturing the particulate matter and suppressing an increase in the pressure loss, thereby preventing the destruction of the ceramic honeycomb structure, and which can also reduce the fuel use that is required to increase the exhaust gas temperature and bring about an enhancement of the fuel efficiency. The exhaust gas purifying filter of the present invention includes a filter body (11) formed from a porous body having an inflow surface through which an exhaust gas containing particulate matter flows in, an emitting surface through which purified gas is emitted, and a number of fine pores, and the filter body (11) has a partition wall (14) and a number of gas flow channels (12) surrounded by the partition wall (14) and extended along the longitudinal direction thereof, and a porous membrane (13) containing at least silicon and carbon is provided on the inner wall surface (12a) of the gas flow channel (12).

A light control element is provided with a thin board having electro-optical effects; an optical waveguide formed on the thin board; and a control electrode for controlling light that passes through the optical waveguide. The light control element performs speed matching between a microwave signal applied to the control electrode and the light, impedance matching of the microwaves, reduction of a driving voltage and high speed operation. In the control electrode of the light control element, a signal electrode and a grounding electrode are arranged on an upper side of the thin board, and on a lower side of the thin board, a second electrode including the grounding electrode is arranged. The second electrode is arranged not to exist below the signal electrode, especially for achieving impedance matching.

Light having components of frequencies f 0 , f +1 and f -1 outputted from an optical modulator (10) is monitored, a second light detection means (14b) measures the power P2 of all the components, and a first light detection means (14a) measures the power P1 with frequency f 0 component cut out by a filter means (13). Based on these light receiving powers (P1) and (P2), phase differences imparted by the respective DC electrodes of Mach-Zehnder optical waveguides (MZ-A, MZ-B, MZ-C) of the optical modulator (10) are controlled. The control is performed to minimize the light receiving power (P1) and to maximize the light receiving power (P2).
