Evanescent field in\r\nthe waveguide is looked as inability of the photon to get confined in\r\nthe waveguide core and uncertainty of position is assigned to it. The\r\nmomentum uncertainty is calculated from position uncertainty.\r\nSchr\u00f6dinger wave equation for the photon is written by incorporating\r\nposition-momentum uncertainty. The equation is solved and field\r\ndistribution in the waveguide is obtained. The field distribution and\r\npower confinement is compared with conventional waveguide theory.\r\nThey were found in good agreement with each other.","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 63, 2012"}
