Dynamic Components

The II-VI S7500 tunable laser incorporates a monolithic InP chip that integrates a tunable MG-Y laser with a semiconductor optical amplifier (SOA). The MG-Y (Modulated Grating Y-branch) laser is an electronically tuned device that can address any wavelength in the C-band. Since no mechanical or thermal adjustments are necessary, channel switching is very fast. The SOA facilitates flexible control of the output power and acts as a shutter when reverse biased, enabling dark tuning between channels. The devices are packaged into a compact, low-profile hermetically sealed package, with an internal optical isolator and a wavelength locker.

100 and 50 GHz tunable filters feature a low insertion loss and a high adjacent channel isolation to minimize the attenuation of the signal transmitted and prevent multi-channel crosstalk respectively. The tunable filter modules are controlled by a digital interface to simplify operational control and system integration.

The MTOF is a Tunable Optical Filter whose passband can be moved along the spectrum through the combination of a MEMS and a grating in order to select the wavelength range to be transmitted. II-VI MTOF is a continuously tunable filter operating over 5THz in C-Band; the L-Band variant is also available.

The MTOF series are tunable optical filters that can be used in various applications to improve the reach of optical transmission systems or for signal monitoring applications. The Mini MTOF is a wideband tunable filter that is ideal for filtering out amplified spontaneous emission (ASE) noise in post-amplified transmitters or pre-amplified receivers. The Mini MTOF incorporates a variable optical attenuator (VOA) function that allows systems designers to improve their receiver dynamic range. The Mini MTOF is uniquely compact and very low cost, which makes it ideal for integration in small transceiver form-factors for 100 Gb/s applications and above.

A Tunable Optical Filter is an optical device whose passband can be moved along the spectrum, allowing the transmission of a selected wavelength band. II-VI ETOF is a compact and low power consumption device based on a dual ethalon cavity, exploiting the Vernier effect and tunable over 5 THz band
