Theoretical analysis of subwavelength high contrast grating reflectors.

چکیده
A simple analytic analysis of the ultra-high reflectivity feature of subwavelength dielectric gratings is developed. The phenomenon of ultra high reflectivity is explained to be a destructive interference effect between the two grating modes. Based on this phenomenon, a design algorithm for broadband grating mirrors is suggested.

Properties of two-dimensional resonant reflectors with zero-contrast gratings.
The spectral properties of high-reflection mirrors imbued with two-dimensional (2D) subwavelength periodicity are investigated. The reflectors are designed in a silicon-on-glass film that is partially etched to implement a zero-contrast interface between the grating pillars and the sublayer, thereby annulling the local reflections and phase changes associated with hard interfaces. This approach...
متن کاملHigh resolution on-chip optical filter array based on double subwavelength grating reflectors.
An optical filter array consisting of vertical narrow-band Fabry-Pérot (FP) resonators formed by two highly reflective high contrast subwavelength grating mirrors is reported. The filters are designed to cover a wide range of operation wavelengths (Δλ/λ = 5%) just by changing the in-plane grating parameters while the device thickness is maintained constant. Operation in the telecom band with tr...
متن کاملStudy on differences between high contrast grating reflectors for TM and TE polarizations and their impact on VCSEL designs.
A theoretical study of differences in broadband high-index-contrast grating (HCG) reflectors for TM and TE polarizations is presented, covering various grating parameters and properties of HCGs. It is shown that the HCG reflectors for TM polarization (TM HCG reflectors) have much thicker grating thicknesses and smaller grating periods than the TE HCG reflectors. This difference is found to orig...
متن کاملIntegrated Optics Using High Contrast Gratings
High contrast grating (HCG) is a new class of optical grating with many distinct features that are not found in conventional gratings [1–6]. These features include broadband ultrahigh reflectivity, broadband ultrahigh transmission, or very high quality factor resonance, for optical beam surface-normal or in oblique incidence to the direction of grating periodicity. Furthermore, these features c...
متن کاملGaN-based surface-emitting lasers using high contrast grating
GaN-based surface-emitting lasers (SELs) using high contrast grating (HCG) with AlN/GaN distributed Bragg reflectors were reported. The laser device achieved a threshold energy density of about 0.56 mJ/cm and the lasing wavelength was at 393.6 nm with a high degree of polarization of 73% at room temperature. The resonant mode and polarization characteristics matched to the theoretical predictio...
