Abstract. In this paper, we present the results of the effort to design and produce a smart home system, PhoneTech. PhoneTech has been designed and built utilizing the telephone network to enable users to remotely control an array of automated home electronic devices by entering a series of commands through phone. The aim of PhoneTech is to provide the users with a better home life experience without overpowering them with complex technologies while keeping the home life as normal as possible.

A new method for optical bandpass filters using macro bending approach is proposed. The proposed optical bandpass filter leverages on bending loss of higher order modes for shorter wavelengths. For longer wavelengths, the filter banks on fiber bending loss as the fundamental mode 'tail' is lost in the cladding. The combination of wavelength dependent loss at longer and shorter wavelength gives rise to the optical bandpass filter characteristics. We report both simulation and experimental results, which demonstrates agreement in the spectral response.
