We review our schemes of subwavelength interferometric lighthography based on classical lights, and show the
procedures to obtain arbitrary subwavelength 2D patterns by multiple exposures. The first scheme is by correlating
wave vector and frequency in a narrow band, multiphoton detection process. The second scheme is by
preparing the system in a position dependent trapping state via phase shifted standing wave patterns.
We propose a scheme that provides all optically controlled steering of light beam. The system is based on steep dispersion of coherently driven medium. Using eikonal equation, we study the steering angle, the spread of optical beam, and the limits set by residual absorption of medium under conditions of electromagnetically induced transparency (EIT). Implementation of another scheme for ultra-short pulses is also discussed.
