“…The theoretical result is also in very good agreement with recently published experimental data on high-speed RCE Schottky photodiodes (Jervase, 2000), , and high-speed Si-based RCE photodetectors (Ozbay, 1997). With reference to Figure 2, the use of the free spectral range (FSR) to the wavelength full width at half maximum (FWHM) as a measure of wavelength selectivity of detection (Kishino, 1991) is no longer valid.…”

“…With reference to Figure 2, the use of the free spectral range (FSR) to the wavelength full width at half maximum (FWHM) as a measure of wavelength selectivity of detection (Kishino, 1991) is no longer valid. The conventional quality factor definition used for filters design defined as the ratio of λ 0 to the FWHM is more appropriate in this case as a measure of selectivity (Jervase, 2000).…”

“…Their quantum efficiency and optical bandwidth characteristics are of major importance in the design of fiber optic based data communication systems. A number of structures and design optimization techniques have been proposed in the literature to achieve high values for these two parameters (Kishino, 1991), (Unlu, 1992(Unlu, , 1995, (Tan, 1995), , (Tung, 1997), (Jervase, 1998(Jervase, , 2000. One of the promising types is the Resonant Cavity Enhanced (RCE) photodetector.…”

“…One of the promising types is the Resonant Cavity Enhanced (RCE) photodetector. In the RCE, the active region is placed inside a Fabry-Perot cavity between two mirrors made of quarter-wave stacks (QWS) to allow the signal light to have more than one absorbing path inside the active region (Kishino, 1991), (Unlu, 1992(Unlu, , 1995, (Tan, 1995), , (Tung, 1997), (Jervase, 1998(Jervase, , 2000, , (Ozbay, 1997). The resulting structure will need only a very thin absorbing intrinsic region to achieve high quantum efficiency as well as a high speed of response.…”

Two key parameters for RCE photodetectors that govern their suitability for ultrafast optical communication systems are considered. These are the quantum efficiency and the bandwidth efficiency product. A closed analytical form has been derived for quantum efficiency, which incorporates the structural parameters of the photodetector. Based on the simulation results, an optimization and design procedure for these photodetectors has been developed.

“…The conventional p -i -n photodiode is not suited to high-speed optical systems that require both high quantum efficiency and high speed of response. 1 One solution to address this trade off incorporating wavelength selectivity is to place a p -i -n diode inside a Fabry-Perot ͑FP͒ cavity and use distributed Bragg reflectors ͑DBR͒ as mirrors, which is popularly known as resonantcavity-enhanced ͑RCE͒ p -i -n photodetectors. 1 The DBR mirrors are usually made of quarter wave stacks with a periodic modulation of refractive indices.…”

The information capacity of a communication system employing a wavelength-division multiplexing scheme can be increased by reducing the free spectral range between different signals, reducing the full width at half maximum (FWHM), and detecting these closely spaced channels. After critically analyzing the design parameters of existing resonant-cavity-enhanced (RCE) p–i–n photodetectors, we have determined that more closely spaced channels can be detected either by increasing the length of a RCE p–i–n detector or by reducing the stop-band width of the bottom mirror. A masking procedure is described to determine the maximum cavity length attainable for any bottom distributed Bragg reflector (DBR) materials so that photodetector filters and detects only one wavelength, being insensitive to all other wavelengths. The optimized cavity length of single wavelength selective RCE detector operating at 1.3μm using 42 12 pairs of InAlGaAs∕InP as a bottom DBR is 7.5μm and its theoretical FWHM is 2.5nm.

The implementation of blue‐light photodiodes based on InGaN in emerging technologies, such as free‐space visible light communication (VLC), requires transformative approaches toward enhanced performance, miniaturization, and integration beyond current Si‐based technologies. This work reports on the design and realization of high‐performance InGaN‐based resonant cavity photodiodes with high‐reflectivity lateral porous GaN distributed Bragg reflectors. The well‐controlled porosification of GaN on the 2‐inch wafers enables design and fabrication of optical components, unlocking the potential of nitride semiconductors for several applications. These resonant‐cavity‐enhanced photodiodes, which have a 12 nm‐thick optically active region, exhibit a high responsivity (≈0.1 A W−1) to blue‐light even without any externally applied voltage. Furthermore, the device can operate as both an emitter and a detector of visible light at well‐defined wavelengths with spectral overlap between the electroluminescence emission and photocurrent responsivity, meeting the requirement of wavelength selectivity, thermal stability, and low‐power consumption for VLC, with potential for integration of different functionalities, that is, light emission and detection, on a single chip without additional light filters.
