“…A convenient approach for modeling VCSOAs is to replace the DBRs by hard mirrors of the same reflectance and use an effective cavity length, which includes the penetration of the optical field into the DBRs [19]. With this method, we can use the well-known FP relationships to describe both the amplifier and wavelength tuning characteristics of the MT-VCSOA.…”

Abstract-We present the signal gain, wavelength tuning characteristics, saturation properties, and noise figure (NF) of MEMS-based widely tunable vertical-cavity semiconductor optical amplifiers (VCSOAs) for various optical cavity designs, and we compare the theoretical results to data generated from a number of experimental devices. Using general Fabry-Pérot relationships, it is possible to model both the wavelength tuning characteristics and the peak signal gain of tunable vertical-cavity amplifiers, while a rate-equation analysis is used to describe the saturation output power and NF as a function of the VCSOA resonant wavelength. Additionally, the basic design principles for an integrated electrostatic actuator are outlined. It is found that MEMS-tunable VCSOAs follow many of the same design trends as fixed-wavelength devices. However, with tunable devices, the effects of varying mirror reflectance and varying single-pass gain associated with the MEMS-based tuning mechanism lead to changing amplifier properties over the wavelength span of the device.

“…For a given scheme, it is possible to define a device-specific figure-of-merit (FOMD), which is determined solely by the characteristics of the microcavity (and not by the particular instrumentation used for interrogation). As an example, in a (17) wavelength interrogation scheme (which is most common) operating in an intensity-noise-limited regime [39]:…”

“…Furthermore, the discussion that follows assumes a symmetric cavity (R1=R2=R) and 'hard-mirror' boundary conditions. In other words, the phase change on reflection, which results in an effective increase in the cavity length for real mirrors [17], is initially neglected.…”

For applications in sensing and cavity-based quantum computing and metrology, openaccess Fabry-Perot cavities -with an air or vacuum gap between a pair of high reflectance mirrors -offer important advantages compared to other types of microcavities. For example, they are inherently tunable using MEMS-based actuation strategies, and they enable atomic emitters or target analytes to be located at high field regions of the optical mode. Integration of curved-mirror Fabry-Perot cavities on chips containing electronic, optoelectronic, and optomechanical elements is a topic of emerging importance. Micro-fabrication techniques can be used to create mirrors with small radius-of-curvature, which is a prerequisite for cavities to support stable, small-volume modes. We review recent progress towards chip-based implementation of such cavities, and highlight their potential to address applications in sensing and cavity quantum electrodynamics.

“…The maximum value of the FSR, which limits the operation bandwidth of LVOF microspectrometer, is half of the reflection bandwidth, Δλ∕2, [17,18]. Increasing the thickness of the cavity layer implies a higher operation mode for the FP structure of the LVOF, which results in higher spectral resolution (smaller FWHM), but a smaller FSR.…”

An IC-compatible linear variable optical filter (LVOF) for application in the UV spectral range between 310 and 400 nm has been fabricated using resist reflow and an optimized dry-etching. The LVOF is mounted on the top of a commercially available CMOS camera to result in a UV microspectrometer. A special calibration technique has been employed that is based on an initial spectral measurement on a xenon lamp. The image recorded on the camera during calibration is used in a signal processing algorithm to reconstruct the spectrum of the mercury lamp and the calibration data is subsequently used in UV spectral measurements. Experiments on a fabricated LVOF-based microspectrometer with this calibration approach implemented reveal a spectral resolution of 0.5 nm.
