“…Further, the analysis of light intensity distribution by a scanning near-field optical microscope shown in Fig. 9 indicates that the full width at half maximum of the light excited from the central aperture is 120 nm and 240 nm, so that this technology can be applied to optical probes using near-field light [13].…”

SUMMARYThe surface emitting laser is one of the leading candidates for a light source supporting next-generation ultrahigh-speed optical linking techniques. However, in surface emitting lasers, especially for the single mode elements, the challenges include increasing the single mode output and stabilizing the polarization direction, and thus the technique for controlling the polarization and transverse modes is important. In this study, we propose a surface emitting laser with a metal nanoscale aperture array whose permeability shows a strong polarization dependence, formed on a p-type semiconductor multilayered film reflector, as a new method for controlling the polarization and transverse modes, and in addition, we explain the potential of its polarization and transverse mode control.

Near-field intensity distribution from a bow-tie aperture VCSEL with its polarization state improved

A micro-aperture vertical-cavity surface-emitting laser (VCSEL) is a kind of active nanophotonics devices. It can confine the optical near-field to a nanometric light spot of high intensity. The confinement effect is usually implemented by a round aperture. A bow-tie aperture can do it better if the incident light polarizes along the line between its ridges. However, a conventional VCSEL does not have a definite polarization state, so a bow-tie aperture VCSEL is very difficult to be implemented. In order to solver this problem, a rectangular aperture array is employed to improve the polarization state. Two bow-tie aperture VCSELs with and without their polarization state improved are fabricated. Their near-field intensity distribution is measured and compared. The measurement results demonstrate that the near-field intensity is enhanced dramatically when the polarization state is improved. So the confinement and enhancement effect of a bow-tie aperture can be obtained on the basis of a micro-aperture VCSEL.

“…In 1999, Afshin Partovi et al [3] invented a light source, that they called a very-small-aperture laser (VSAL) on a 980 nm laser diode with a metal-coated facet, in which a small aperture had been formed. However, the optical near-field intensity from the aperture in a VSAL is so far not strong enough for writing and reading data [4,5]. In order to increase the efficiency and the output power, Goto [6] proposed a kind of near-field memory that uses a vertical-cavity surfaceemitting laser (VCSEL) array, which can overcome the previous limitation and enable high-density, high-speed parallel recording.…”

Surface plasmon modulated nano-aperture vertical-cavity surface-emitting laser

Abstract:We have fabricated surface plasmon modulated nanoaperture vertical-cavity surface-emitting lasers (VCSELs) from common 850 nm VCSELs using focus ion beam etching with Ga + ion source. The far-field output power is about 0.3 mW at a driving current of 15 mA with a sub-wavelength aperture surrounded by concentric periodic grooves. The enhancement of transmission intensity can be explained by diffraction and enhanced fields associated with surface plasmon. This structure also exhibits beaming properties.Nano-aperture SEM photograph of a nano-aperture surrounded by concentric periodic grooves
