“…The quality of commercial silicon on insulator (SOI) wafers driven by the microelectronics industry still continues to improve while the cost continues to decrease. Moreover, as previously mentioned the compatibility with silicon integrated circuits manufacturing is an important reason for this interest in silicon photonics [1].…”

An analytical model of the silicon on insulator photoactivated modulator (SOI-PAM) device is presented in order to describe the concept of this novel device in which the information is electronic while the modulation command is optical. The model, relying on the classic Shockley’s analysis, is simple and useful for analyzing and synthesizing the voltage-current relations of the device at low drain voltage. Analytical expressions were derived for the output current as function of the input drain and gate voltages with a parameterization of the physical values such as the doping concentrations, channel and oxide thicknesses, and the optical control energy. A prototype SOI-PAM device having an area of 4 μm × 3 μm with known parameters is used to experimentally validate and support the model. Finally, the model allows the understanding of the physical mechanisms inside the device for both dark and under illumination conditions, and it will be used to optimize and to find the performance limits of the device.

“…However, please note that this complexity can be handled in three ways. First, it can be reduced by using all-optical processing modules based upon photo-refractive effects which can reduce the number of needed detectors (as basic Boolean logic can be realized in all-optical manners and then the 'flash' ADC will become a real ADC) [17,18] and, secondly, the applicability of the proposed novel architecture does not have to be suitable only for applications in front-and high-end coherent optical receivers. For instance, one application for the proposed ADC could be all-optical smart-routing networks in which the conversion is needed not to process the data itself but rather to optimize the routing architecture of the optical network which is changing in time at much slower rates while the information that needs to be analysed for the monitoring purposes is at high rates.…”

A novel ADC configuration that can be characterized as a photonic-domain flash analog-to-digital convertor operating based upon free-space interferometry is proposed and analysed. The structure can be used as the front-end of a coherent receiver as well as for other applications. Two configurations are considered: the first, ‘direct free-space interference’, allows simultaneous measuring of the optical phase and amplitude; the second, ‘extraction of the ac component of interference by means of pixel-by-pixel balanced photodetection’, allows only phase digitization but with significantly higher sensitivity. For both proposed configurations, we present Monte Carlo estimations of the performance limitations, due to optical noise and photo-current noise, at sampling rates of 60 giga-samples per second. In terms of bit resolution, we simulated multiple cases with growing complexity of up to 4 bits for the amplitude and up to 6 bits for the phase. The simulations show that the digitization errors in the optical domain can be reduced to levels close to the quantization noise limits. Preliminary experimental results validate the fundamentals of the proposed idea.

“…Amplifikasi daya pada DFA bergantung pada dimensi panjang doped fiber, semakin panjang doped fiber-nya maka amplifikasi dayanya menjadi semakin besar. Salah satu material aktif yang memiliki kemampuan mengamplifikasi foton adalah Erbium (Er 3+ ), sehingga sistem penguat intensitas daya optik sering disebut dengan Erbium Doped Fiber Amplifier (EDFA) (Rudnitsky, 2011).…”

Abstrak: Material nonlinear menjadi material kunci atas teknologi komunikasi dan informasi modern. Perkembangan dunia optoelektronik seperti ultrafast switching, modulasi informasi berkapasitas tinggi, gerbang logika berbasis optik, dan pandu gelombang pembagi daya adalah aplikasi langsung dari material nonlinear. Dalam praktik pemanfaatan material nonlinear, sumber cahaya memiliki peran sentral. Hal ini disebabkan oleh amplifikasi intensitas sumber cahaya dapat menyebabkan munculnya efek nonlinear. Selama ini amplifikasi intensitas cahaya tersebut dilakukan melalui doped fiber amplifier (DFA). Harga EDFA di pasaran cukup mahal dan rancang bangun sistem penguatan optik EDFA juga memerlukan biaya yang sangat tinggi, termasuk pengadaan tools dan instrumen optik yang digunakan. Pada penelitian ini dirancang suatu alat yang mampu melakukan amplifikasi intensitas intensitas dengan biaya yang relatif ekonomis, yakni berbasis laser dioda dan menggunakan prinsip superposisi gelombang. Dalam pengujian melalui optical power meter, telah didapatkan nilai intensitas yang berasal dari 6 laser Visual Fault Locator yang dikopel menggunakan 1x8 splitter. Tanpa adanya kontrol fase, diperoleh hasil bahwa banyaknya laser yang menghasilkan intensitas terbesar adalah kombinasi 3 laser. Sedangkan, pada kombinasi 6 laser diperoleh daya yang lebih rendah dibandingkan daya 1 laser, hal ini menandakan bahwa kontrol fase menjadi sangat penting agar interferensi konstruktif dapat terjadi.Kata kunci: laser dioda, metode side-by-side combining, interferensi konstruktif, material nonlinear
