“…2,3 However, most of the investigations have been carried out to study ASE sources of Ͻ200 mW ͑23 dBm͒ with the fiber-grating-based and fiber-mirror configurations under specific designs, [4][5][6] which also take the advantage of EDF as the gain medium to amplify the feedback wavelength in both of the conventional wavelength band ͑C-band͒ and the long wavelength band ͑L-band͒.…”

We have investigated and experimentally demonstrated highpower and stable C-band and L-band erbium-doped fiber amplified spontaneous emission ͑ASE͒ sources using a multipumping configuration, which can provide an output power of 27.16 dBm ͑519.99 mW͒ and 27.34 dBm ͑542.01 mW͒ with a power ripple of 5.9 and 1.1 dB for C-band and L-band without adding any external spectra-flattening components. Moreover, the averaged power stability of C-band and L-band erbium-doped fiber ASE source with ±0.005 and ±0.003 dB during an 8-h interval measurements at the room temperature 25°C can be achieved, allowing high pumping efficiency of 38.5 and 36.9%.

“…Superluminescent diodes (SLDs) with high output power and wide optical bandwidth performance serve as key components for applications of optical coherence tomography (OCT) [1] and low-cost fiber communication systems [2]. In traditional vertical junction (VJ) SLDs with several nonidentical multiple quantum wells (MQWs) [3,4] or quantum dots (QDs) [5,6], the electroluminescence (EL) spectrum is strongly governed by the center wavelength of the QWs or QDs near the p side due to the nonuniform distribution of injected carriers among these MQWs or QDs.…”

We demonstrate, for the first time to our knowledge, GaAs-based transverse-junction (TJ) superluminescent diodes (SLDs) that operate at a wavelength of 1.1 microm. Due to lateral current injection by use of TJ, specified as transverse carrier flow spread in each quantum well horizontally instead of vertical well-by-well injection, nonuniform carrier distribution can be minimized among different multiple quantum wells (MQWs), which is a problem in vertical-junction (VJ) SLDs whose electroluminescent (EL) spectrum is governed by the center wavelength of QWs near the p side. In contrast with a VJ SLD, the EL spectrum of our device is determined by QWs that have a larger differential gain than the positions of QWs neighbored with a p side layer.

“…Thus, the wavelength alignment among the sources, a multiplexer, and a demultiplexer is essential. Especially, the amplified spontaneous emission (ASE)-injected Fabry-Perot laser diode (FP-LD) has opened the commercial possibility as a low-cost transmitter with its automatic wavelength locking to the arrayed waveguide grating (AWG) passband [3][4][5], i.e., making it "colorless". Therefore, in the WDM-PON employing ASE-injected FP-LDs, the wavelength alignment between the source and a multiplexer is automatically solved.…”

Adjacent crosstalk suppression in a colorless WDM passive optical network

et al. 2007

We propose and experimentally demonstrate a novel wavelength-division- multiplexed passive optical network (WDM-PON) scheme for the suppression of adjacent crosstalk arising from the wavelength misalignment in arrayed waveguide gratings (AWGs) between a central office (CO) and a remote node (RN). The adjacent crosstalk suppression is achieved by allocating two different bands to adjacent channels of the AWGs by utilizing interleavers and WDM filters. The transmission performance of the proposed scheme was measured at a 155 Mb/s data stream, and error free transmission with a power penalty less than 0.7 dB was successfully achieved in case of AWG misalignment of 0.3 nm.
