“…This phenomenon was previously reported in Ref. 3 where we found that slit apertures have an effective height that is more or less defined by the extent of the optical mode width rather than the height of the aperture. This result is consistent with the manufacturer provided data and is about 0.2 m.…”

We report on the effect of different aperture shapes on the power output of a very small aperture laser (VSAL) fabricated from commercial edge-emitting laser diodes and correlate the results to the layer structure and polarization of the optical field. A waveguide theory is used to explain the experimental observations. We show that the shape of the aperture has a significant effect on the VSAL output power. In particular shapes exploiting the asymmetry of the laser can achieve much higher throughput over square apertures while keeping the aperture area constant. This work also indicates the validity of analyzing near-field small apertures as cutoff waveguide structures.

“…1 Previously, we reported on a method of fabricating VSALs from commercial edge emitting lasers. 3 In principle, the final aperture size primarily determines the recording mark size. With high resolution FIB etching, an aperture size of 10 nm is achievable.…”

“…Unfortunately, if the diameter is smaller than λ/2, the aperture does not support propagating modes, and the transmittance is then small (tunneling is necessarily part of the transmission mechanism). Consequently, the output power through the small aperture is so weak that it cannot be applied to read or write data on a CD or DVD [3].…”

Oil-immersion or solid-immersion power enhancement of very-small-aperture lasers

2006

An analysis of the enhancement of light transmission through a sub-wavelength aperture by oil- or solid-immersion is presented in this letter. An output power enhancement phenomenon related to the oil-immersion or solid-immersion mechanism is realized experimentally and reported for a very-small-aperture laser, which is in agreement with simulation analysis. This phenomenon could be useful for future optical data storage, microscopy and lithography.

“…Since then, many papers have been published about the devices. Researchers have tried to make such devices with high output power by employing semiconductor edge emitting lasers or vertical cavity surface emitting lasers [2][3][4]. They changed the shape of the small aperture [5], the wavelength of incident light [6], and the material filled in the small aperture [7], etc.…”

Detect the sub-wavelength data by applying a very-small-aperture laser

et al. 2005

We present a theoretical and experimental research about applying a very-small-aperture laser (VSAL) to detect sub-wavelength data. Near-field distribution of a VSAL, which is essential for the application of such near-field devices, will be affected by the sample or fiber posited in the near-field region of the aperture. When the device is applied to detect the sub-wavelength data, the real resolution depends on the near-field spot size, the divergent angle of the beam and the distance from the aperture to the sample. Experimental results, including the near-field detection of the spot and detection of the sub-wavelength data by using the VSAL, are presented in this paper. We realize the two dimensional scanning about the sub-wavelength data (with the width 600 nm) by employing a VSAL with a 300 nm×300 nm aperture.
