We studied the role of the aperture depth on the enhanced transmission of light through subwavelength holes in free-standing Ag films by measuring the transmission properties of square arrays of cylindrical holes. Two regimes are found which give insight into the transmission mechanism and will be of importance for device applications.

    The substituent effect on photochemical hole burning (PHB) for tetraphenylporphine was studied and the PHB efficiency was related to the electron donating and/or withdrawing properties of the substituents of the phenyl ring.
